For a 69 GTO. Any thoughts or recommendations on which is the best, authentic to factory specs, window felt kits out on the market. I have been told to stay away from PUI products and am leaning towards Repops Automotive Reproductions. OPG carries PUI, and Ames stated they have a gentleman who reproduces them EXACTLY like the factory, but wouldn't give out his name. Kinda leery if they won't give out who manufactures them and, if it isn't what they say it is as far as being authentic, I would have to pay for return shipping. Has anyone purchased them from Ames and if so, "authentic" or not? Thanks in advance.
