The letter cars are no different than any other C body in terms of construction. A Newport before a 300 isn't any less well made. The power is no different than B bodies, with the obvious exception of a Hemi. The big barges do float down the road nicely, I can attest to that. The biggest challenge is finding good sheet metal or trim pieces. We don't have the luxury of aftermarket support. I learned it's easier to get an entire parts car for a few pieces rather than find the pieces. Selling off the leftovers I don't need gets me some money back in my pocket. But we fall into the trap of a parts car becoming another road worthy car after we deem it too nice to cut up, that's how we end up with a fleet of C bodies. :BangHead:
