I lost my original Pillars from an iniital restoration guy who threw them??? or sold them???
My car 1967 SS Chevelle. I was told I could replace by finding ANY 66, or 67 A frame Convertible cars Pillar molds. This sounds easier than it was. I did find and paid well for the Pillar molds and the casing that holds the trim for around $175.00 used but good condition. I called all across the country but had success here:
The guy went into one of their warehouses and manualy found them as He has a 66 and needed the same last year.
If they don't have it, they'll find it within some time.
Good luck and PS. I was never able to find anyone that re-popped these. No One!!!
