Oddball car - swap to disc - ideas?

I've heard that but it always seems like somebody has an exception, usually because somebody else has gotten their mitts on the car. I'm sure that Mopar tried to use up all the parts they had on these things though. I bought a slant 73 Duster body once with no doors for $75 mainly because somebody wanted big bolt pattern so bad they put the KH 340 disc setup on it from a swap! CHACHING!

Yeah exactly. This is 43 years down the road from 1973, so who knows what someone might have done. For awhile drag racers were changing disk cars to drums because of the lower rolling resistance. And then there's former parts cars that had BBP disks swapped for '72 down drums to swap the earlier car to BBP disks and keep the "parts" car rolling. I've read posts where someone had a 73+ V8 car with front SBP drums that swore it proved they had them from the factory, but according to all the literature they didn't. Only /6 cars with manual brakes got SBP, 10" front drums from '73 to the end of calendar year 1975 (not model year!), from Jan. 1976 everything got disks up front by law. Someone just swapped them at some point, who knows why. Between that and Ma Mopar's tendency to use up leftover parts before a changeover, there's probably some exceptions out there. Or at least cars that might seem to be exceptions.
