Restoration Specialties ?

I like to deal with Restoration Specialties too. I have for many years.
In relation to Precision, several years ago there were no windshield or back glass seals to be found for early Barracudas. Every shop I called gave me the same story, Precision Replacement Parts had a facility burn so production was down, gaskets were on back order and there was no telling when Precision would supply them again. I finally asked Restoration Specialties if they would call me when they got some in. Sure enough, some time later they called and told me they had received a shipment of early A stuff from Precision Replacement Parts so I ordered the seals I needed. In a couple of weeks the seals were available from many suppliers and even appeared on E-bay. So it seems that Precision is the manufacturer/supplier for a lot of the glass related weatherstripping.
