Re: Need correct screws to attach top bows on a '35 12 coupe-roadster

I don't have documentation, but I think originally those were very precise fitting flat head wood screws so that the finished surface was smooth to the touch. That all goes out the window once the parts go to a plating shop.

Those screws should be attaching the mechanism to the wooden side bar so there are a couple of options. The quick and dirty method is to cram some wooden match sticks into the holes using carpenter's glue, drill a pilot hole, and run a screw in using soap as a lubricant. The second method is to detach the metal parts and glue dowel stock in place and then drill a new pilot hole for the screw. When drilling for the dowel stock either a depth stop on the drill bit or a protective metal plate should be used to prevent damaging the canvas top.

You can remove one of the remaining screws to verify the screws are securing the metal to wood.
