While at the Pittsburgh Vintage races and car show this past July, the MB classic center had a display tent, and were handing out the price sheets for all the parts,manuals, etc books. Along with this they gave me a CD that did the conversion from the parts numbers as listed in the old style parts number to the new ones (with the letter in front) that the web site requires. All you do is boot up the disc, type in the old number in the slot provided and hit the search button, if there is a new listing, it pops up. I am traveling this week and do not have the CD available to look at to give you any further references numbers etc. I will do that when I get back this weekend.
