Wheels/Tires would be fairly easy; some of the smaller bits like the very fragile headers (which are different after "Street T" ) are more of a challenge due to thin section and low thermal mass.
Reportedly, the next vintage hot rod project on the list before the Black Friday at R-M/Hobbico after Blue Bandito restoration; maybe Ed can prevail upon the home office to support? Were they to reissue the Big T, then I could see a good business case.
I keep harping on 3D, but this is a great opportunity; with the advent of the spray chromes, don't need to offer the parts plated.
