I am getting ready to cut these rust free A Pillars off, great to repair your rusted out windshield sides channels. Will work for most of it for a convertible, I believe 68 would have been different on the inner area since they had the vent window assemblies. I normally cut into the roof about 2 inches in on the side and front given you the corner, price is $100.00 per side or 185.00 pair, very hard to find. Last pic is an example of previous sale showing you how it was cut. Shipping will be 30.00, Paypal accepted as sales, Joe 602-298-7090 vegaazbowties@aol.com
Also have the sections that are under these and make up the corners of the top cowl and lower windshield for $45.00 per side, rust free.
