Wow thanks so much Al, loads of detail. I knew I would have to some reinforcing of the “X” member frame work, wasn’t aware of the engine mounting details and the radiator mounting bracket! I have a possible complete ‘53 56r rolling chassis, engine and dynaflow tranny that I am considering mounting the ‘52 56c on and convert to 12volt. The other is putting my straight 8 263 in mated up with the ‘53 dynaflow and keep the car 6 volts. I am leaning towards dropping both the original ‘52 straight 8 and tranny in this roller frame, hooking it up to the torque tube and rear end that’s on the roller. Question, is there any difference in the torque tubes between these two cars? I really want to keep this car as original as I possibly can. Thank you for your help and advice.
