I'm sure they have the same kit for your car too

Have looked nationwide cheapest kit is 220 or so. Cant even find any used ones. So frustrated

It appears to be poured in a liquid state into the aluminum casting. I don't recall ridges or any other retaining features.

Oh! I just remembered that a wrecking yard up here has an 87 300dl. I went up there to check it out and the motor is gone but maybe the metal piece from the shock is still on there.
If they don't have it, ask them to check their parts interchange system and they can tell you all the other models that have the same engine shock.
Then you can get the rubbers and everything from Discount Import (or elsewhere).

The wrecking yard is called All American Classics and it's in Vancouver, WA

I used a bench vise to press the homemade discs into place, or you could use a "C" clamp.

thanks i actually think i saw the junkyard you mentioned online i called and they are closed mondays so am calling them tomorrow. May have to go the route of candide if i cant find any

If you get desperate I have an old Book: How to Cast Small Metal & Rubber Parts.
For the Rubber you use Flexane (Urathane) made by Devcon. It can be a pourable liquid or a putty. But, it is not cheap.
Added Note: I have no experience with the above product.

To get some idea of the price look on Ebay.
Flexane 60 high flexability, 80 medium flex, 94 low flex

Some articles I pulled off of the Net:

Thanks for all of the input and advice from everyone...do believe i will be going the route diesel911 suggested and ordered flexane 80. Read articles where it was used for engine mounts for 7 years without any issue....i figure if it can handle that much abuse it will work great poured into my mount. Will be doing this soon and will post results for others maybe can save some people some money.
