I agree with Bill that your target market would be Factory Five as they have sold more cars than any other replica manufacturer. I think even that would be small segment of them though. Originalists want aluminum bodies and a lot of FFR owners aren't overly obsessed with originality. The frame would have to modified to add the AL body as there's no tubing around the cockpit to support the body. Door/hood/trunk frames would also have to be made and skinned in AL to fit.
Now maybe THAT would be something more profitable... pre-made door/hood/trunk frames skinned in AL to fit FFR. Something to think about.
