I am going to need to replace the door glass on a 1981 Brat. While I am at it I need to replace the window channel felts, rubber wipers , etc. Where is the best place to find these items? I am more accustomed to specialty catalogs for old Fords and was wondering if there are good suppliers for soobie stuff like this too. Or do most auto glass outfits carry/order this stuff since the cars are not really that old?

The first place to check is with a Dealer. Having said that, its VERY likely that all of these soft parts have long since vacated the warehouses. So the next source is your local autoglass dealer. They may not have direct replacements, but they will likely have the correct materials on hand (or orderable) to make new ones for you.
