I used to feel the same way. But now I prefer that the really old originals (1920s and 30s particularly) should be preserved/restored as original. Not that I don't love them as hot rods, but, in their case, as increasingly rare as they are, I would rather use a reproduction than original metal for that purpose.
Probably running out of basket cases to convert into rods and customs for many of these makes and models, true. I’d never advocate molesting a complete, restored original of anything. But, the reproductions and replicas still lack authenticity to me. I suppose I’ll just have to get over it, lol.
