I also have a 1990 300E that needs the conversion kit. Can you tell me what parts come in the kit. Your post does not mention any new parts as part of the kit. I live in New York City and was quoted a price of about $400.00 parts and labor. Mercedes dealers would charge about $700.00. Can you reccommend a major auto chain that can do a compentent job?
I found your post by doing a Google search.

Thank you,
