They were out of Michigan, listed as the Ventre corporation of Mt. Clemens Michigan. Looks like they made asstd accessories like spoilers and window louvers. It really is a solid looking construction on it.We put a few of them on back in the day. I thought they were one of the best fitting aftermarket options available back then.
Did it say where they were located? I’m thinking ours came from Michigan, but that may have been the vendor.
