Just put a bid on an authentic period correct AMG badge to replace the current ///AMG badge.

http://www.ebay.com/itm/AMG-Mercedes-Pre-Merger-STYLE-VTG-Classic-W124-W126-W116-R107-emblem-badge-logo-/253002559110?hash=item3ae820ae86:g:-2YAAOSwOMdZSZku&vxp=mtr

Also thinking of removing the tacky ///AMG badges on the front lower trim panels and replacing it with them H&R stickers. Anxiously awaiting the rest of the front end parts.

Just got my tire balancer installed and anchored to the floor.. Getting ready to calibrate the unit right now. I'll be happy because nothing like a well balanced set of tires to keep that ride as smooth as possible. I have to admit, I think these springs are going to drop the vehicle quite a bit.. I will set a stock set of springs next to these in my W126 H&R spring installation thread. Mulling getting some new shocks... Not sure, I got lots of real nice factory ones.. I'll have to see how much different stock springs are to these 1.4 inch drop H&R units and I'll decide then.

Cool. There's nothing wrong with fitting new shocks, though your old ones may feel new, as they'll be resting / working in a new location. ( At least the plunger & body will ).

Often lowered spring-sets will come with compatible rubber cushions, that will be often much larger than the original rubbers. This may give you some height back.

I am going to take height measurements before and after... all 4 wheel arches.

You can always expect a few more millimeters lower again, should the 560 motor & trans find a home in there. It would be a heavier package for sure than the 420 coming out of it.

Yes I was thinking the same thing..

And some more good news, pre-merger AMG badge seller accepted my offer, so it looks like the improper ///AMG badge is now a wall ornament.

Well I got the last batch of parts this morning... Now with any luck I will be caught up on customer pay repairs and I can bring in the 1975 Stingray and the Mercedes to start doing some fun work! 

Got my tire machine up and going, calibrated it with the 100g plumb weight and it works like a charm! Looking forward to taking the next month and getting the garage ready for winter.. read that as forced air heater, new hard airlines ran, insulation and hollowing out the roof to allow another 4 feet of lift. Hopefully the next few weeks will slow down a bit so I can get it all finished in time... Usually it does around this time as the weather starts to cool a bit. The last week felt like a heatwave with temps in the mid 90's!

Well, I got home excited to do the Mercedes only to find that miraculously, the steering rack on the Cadillac DTS was broken clean in half!

So I asked my oldest, WTF happened to the Cadillac? To which he responds, "I dunno Dad, maybe you turned the steering wheel too hard"? All this with a straight face...

Needless to say the Mercedes 420 was immediately re-instaed to daily driver status since I now have nothing but the Corvette and the weather has taken a turn for the worst. Good thing for me these old W126's are as reliable as they come and I haven't missed a beat, despite my "Turning the steering wheel too hard" in the Cadillac... 

Now, to add insult to injury - my youngest went shopping for a Halloween costume with his Mom and come back with this outfit, obviously an effort to mock me...

Oh well, ordered a new rack, control arms and hub bearings for the Cadillac and I'll have to fix that... Meanwhile ole' reliable will be pimping out...

"Maybe YOU turned the steering-wheel too hard" ?...

You did mention that you were wondering what your boys were up to while you were on your vacation...I guess this a hint at some-of-the-stuff LOL !!!

IT COULD HAVE BEEN MUCH WORSE LOL !!!

I'd be contented with a broken steering rack I think...But to do that to it is a pretty hard knock, & it may well be time to pass-it-on once repaired...

Yeah, I find it very odd and peculiar as well... but... what are you going to do.. Doesn't appear to be any rim damage, unless they thought to rotate the bent rim to the rear... noticed they switched the plate from the Cadillac to the Mercedes... So that was a bit odd... I think it should be fine once fixed as I picked up a lot of extra goodies such as wheel bearings, lower control arms and an entire rack with inners and outers with new stabilizer bar end links. Also, as I mentioned the tire balancer is up and running so I can balance out the tires real nice... I think it will be fine and besides, it's just for them really deep $hitty days so I don't have to plow snow with that AMG bumper and them new lowering springs.

On the bright side, at least the period correct AMG badge showed up!

No thanks to the kid I now have them H&R stickers that I wanted to put on the front lower fenders stuck on the side of a new soap bottle that I purchased for the tire machine... Just where I wanted it! THANKS! lol... can't have nothing.

Somehow I envision this when I think about what happened to the Cadillac while I was away...

You see, the guy just turned the wheel too hard... Same thing here

Meanwhile, several hundred dollars later -

I'm looking down the barrel of lowering the cradle to install this stuff.. jeez... one step forward, two steps back!

You don't mess around fixing stuff LOL !

The second clip ( Star Wars ) is almost believable....

The Mercedes looks pretty good in the photo...10-times better than the car in the back-ground with miss-matched paint-work !

Thanks Rastus, that S-10 in the background is not my car... it was just a car in the parking lot where I first purchased the car in Redford.

It's been a real task catching up from my little "vacation" and I can only thank the Mercedes Benz engineers for the reliable beast for without it, right now I'd be walking or driving someone else's vehicle. I was just telling the wife that the W126 reminds me of the Terminator, in that it will keep going and going upon your command until one of you are dead. True story.

Each day as I am turning the customer pay wrench I have to look at all these glorious parts stacked in a pile in the garage. It's pure torture I tell you! LOL

Well, in a pinch I installed just the rack and pinion with the outer tie rod ends... held off on the control arms and wheel bearings until I could get caught up.

So I get that done in record time and proceed to drive the car for two days and now the transmission has $hit the bed! lol! I must have REALLY turned that wheel hard! Seems she is now pumping transmission fluid out of the front transmission seal... So, lucky for me I happen to have one sitting in the corner ready for install out of a DHS parts car I purchased awhile back for center hub caps of all things! LOL, hey it was $50 each for the wheel covers of $300 for the whole car... 

Still having major issues with the Mercedes Benz 420 SEL heater system and I have taken some photos of the ridiculousness that they call a W126 HVAC system... Apparently every single W126 build from at least 1986-up regardless if it's an American or European vehicle has a dual climate heater core.... Only thing missing to have dual climate control would be the duo-valve and some kind of regulation of it... Don't worry, I am not interested in dual zone climate control, or re-inventing the wheel but I'll soon be posting some pretty interesting HVAC photos in a separate thread...

So that's where we stand... So far the Cadillac has required 5 more repairs, and is still in need of yet another to be roadworthy. Meanwhile the Mercedes, while only having one side of the heater working (see my next HVAC thread), has managed to maintain a drivable state without any repairs... That's not to say it doesn't need some, just that it's able to carry on without leaving one stranded, albeit maybe a little cold on the drivers side... LOL

I have started a new thread for the Cadillac woes,

http://autotrend.activeboard.com/t64188508/2000-cadillac-dts-project-northstar-46-dohc-32-valve/

so it would appear the path of least resistance may end up being the Mercedes since the problems on that car have taken a real turn for the worst...

Getting back on Mercedes topic, I am having a hell of a time with this climate system... Having to dig quite deep! 

Basically, the heater problems on the Mercedes have reached full circle as my efforts to just bypass the entire mono-valve, pump and valve assembly to see if the core was quite informative. In an effort to just get heat and see if the core was flowing coolant I tried to pump coolant from the engine port to one of the two lines that enters the heater core using a 90 degree fitting and plugging the other hose.. come to find out these damn W126 cars come with dual zone heater cores! LOL, they have two lines going in and one coming out of the bottom!

Here you can see the three heater core lines.. important to realize here is that most vehicles only have two. At this time I believe the two inlet hoses are on top and the return on the bottom however I may come to find out otherwise later. Keep in mind, this HVAC box shown in one of the many I have from donor cars and I took this one apart just to see how it worked and I was shocked to see these HVAC boxes don't really have a "blend air door" like most cars, rather the car relies mostly on the mono valve controlling or preventing flow to the core to regulate temperatures since the heater core and AC evaporator core are basically stacked upon on another. 

Here you can see my handwork putting in a 90 degree elbow.

Here you can see the plug that was installed on the other hose to keep coolant from leaking.

In this configuration, with just the one side being hooked up, only the right hand side heat works which corresponds to the inlet position of the hose. So basically every Mercedes W126 is set up with a heater core for dual climate control! US versions however lack the second valve and controls to utilize this built in feature and I wonder if that is why the mono-valves are so problematic in this configuration.
