I don’t know of a company who makes a kit for all the clips. The only factory clips you will need on your ’55 are the rocker panel molding clips and the roof rail clips. All of the other stainless (quarter panels, fenders, doors, hood) can use the universal clips that bolt on). You can get them in various sizes at any parts store and for a whole lot less money than the factory clips. When I did my ’55 a few years back I got the roof rail and rocker panel clips from a gentleman in Whittier, CA. His name was Guy. I reached him at 310 696 3307. I don’t know if he is still in business as this was almost 20 years ago. I think some of our suppliers (Mercuryland, MACS, Dennis Carpenter) may also have these clips or know where you can get them. Good luck.
