A friend of mine recently picked up some parts but he can't ID these, can anybody help. Looks like the body mount for the convertible top frame is cast aluminum and has an overall length of 71". From side to side it is 52" It has 6 twist snaps and 12 mounting holes. It looks like the 4 strengthener pieces for the top frame go with the mounting piece but can't be sure. One of the 4 pieces is solid the rest are hollow. There are no markings or numbers on anything. Don't know if this is American, British, German, Italian, French. Anybody have a stab in the dark as to what they belong to. Looks like it would go to a larger convertible and not an LBC
