I was one of the first Bosch Authorized Service Centers in the US back in the mid 80s but I retired sometime ago. In going through some of my storage
I found the following items that might be of some use to folks or shops working on "older" Mercedes and BMW. Almost all of these
are NEW or as new with their original Bosch boxes. I am sorry that I do not have more descriptions but my memory is not what it used to be.
Reasonable offers entertained. You may reach me at twigwork@charter.net but please mark your email header as BOSCH INTERFACE ITEMS
so that I don't miss it. Thank you, Jack
