What type of stainless steel inserts are you looking for? If you want to do a silver crested, which I'm not sure if they had in 1960, you're best bet is to go to a sheet metal supplier, and have them cut the stainless to fit your top. Brand new, and probably a lot cheaper than looking for an original roof. I was going to do this on my '59, but decided it was too many textures, since the landau bar is also faux vinyl texture.
