I bought a couple of tops from JC quite a few years ago .Then they had different grades. It's a lot of work so I bought the best grade. It lasted 10 years outside all the time. Jc used to buy from the mfg on the east coast .. I called the Mfg when I needed new side curtains that weren't in the JC catalog any more but they only sold to their dealers. In the west Keystone is a large upholstery compamy that sells mostly to shops..you might check for suppliers in your area. I've done a couple of tops from scratch and they are a lot of work. My 29 A roadster has a 2 inch chop windshield and the guy said the new top bows are from a 32, Still a long time until the trim work and I don't know if I can make a 32 kit fit.
