BlackMercedes- that's a 360TE AMG , no turodiesels (TD) here

Regarding the 3.07 limited-slip diff, yes I have one in the wagon, and it's from a 1986 Euro 190E 16-valve. It is the "smaller" differential (lubricant capacity 1.5-liters), but has been reinforced and rebuilt by Rick of RC Imports in Rockville, MD. Rick is a MB shop-owner and a MB racer: http://www.rc-imports.com/

With an AMG'd M104 (aka, C36 engine) which is similar in HP and torque to a 4.0L M119 engine (W124 400E, E420), the wagon with 3.07 rear-end is faster to 90-100 MPH than our 1993 500E from a stand-still.

A 400E with a 3.07 would beat a 500E to the quarter-mile.

The gentleman in Denver with a 400E with 3.07 gears is indeed Stu Ritter. He sold his shop to one of his technicians and is in retirement. Yes, he used the innards of a 450SL or SLC to replace the innards of his 400E diff to give it 3.07 gears and limited-slip.

If you do this route, you need to find a shop that has the proper tools and experience. Rick of RC-Imports has this experience. BTW- the 400E/500E use the "larger" diff with a lubricant capacity of approx. 2-liters.

You are in a good position to do this because your 400E doesn't have ASR.

I've yet to figure out how to do this to our 500E, without getting a new one from Mercedes or RennTech.

Once you have the diff, installation is fairly easy.

Good luck,
