Where can I find clips for the body molding on a 1986 Cutlass Supreme ?
That's a tough one, sometimes the dealer will have those parts, possibly the salvage yards. But if they are the common clips, go to the "Help" section in your local auto parts store and match them up. You should be able to find clips and nylon fasteners for just about any car.
