Do you have GM Vintage Services documentation for your car? Costs money, but will give you valuable info on it's build and some production numbers (no info on SD, though). Second 'sticky' from the top in the Canadian Forum is a link to this documentation service.Geez, the more I read about the Acadian SD, the more bad I feel for even suggesting that I convert it to a Nova SS. Apparently no records were kept on production numbers of the SD model, but estimates are somewhere between 100-400 produced, which is crazy, when thinking about the tens of thousands of Novas made. So I decided to spend the money and get it professionally restored (as an Acadian). Only problem is, we can't find the wide fender/door trim. Didn't realize how rare it really was.
As for the side trim, check with Menno Weisehahn in Aldergrove, B.C. He has a big stash of Acadian parts. He may not have this trim, but can give you some other contacts. He's at 604-856-5526 or [email protected]
