Okay, the dealers I called couldn't give me all the old part numbers because their computers look forward not backwards; however, EZL's from the following cars should work in any 500E/E500:

1. Any 92-95 500E/E500

2. Any SL500 up to 97

3. Only 92-93 500SEL's, and

4, Only 92-94 S500s.

I hope I've saved some poor soul a lot of trouble, not to mention a few grand. Thanks to everyone who shared their input.
