Someone will correct me quickly, I hope.
You might have to put the correct (216-truck-style) front motor mount on the 235.
Put the 53 truck 216 pressure plate, clutch assembly, and bell housing on the 62 (Belair) 235.
Mount the 53 foot-starter assembly on the 53 216 truck bell housing.
The 53 truck 6v starter will work fine.
Someone, please quickly correct me if I am wrong.
Tim
