Does anyone know where I can obtain a parts book, or CD for a 1991 350 SDL ? Are there any websites that have parts lists showing part numbers. When I try to explain over the phone what I need, it ends up being like I am trying to get a haircut over the phone ! I am 300 miles from the nearest dealer.

Check with speedy300Dturbo on sourcing the MB EPC.
