and now, there are complete 57 chevys, camaros, and mustang bodies [challenger maybe too ?] that just "require you to "supply" a "proper set" of numbers to then register as an original vehicle. all claim to be so authentic in construction you couldn't tell from original. spotweld types and locations, panel fitment, basic chassis welds and their nuances, etc. i'm curious how many of these have been sold, and if any hassles were encountered when it came time to go to the state dmv ?
