Can anyone tell me the MAIN differences between a frame from a 46 Chevy truck frame and a 48/53 Chevy frame??? I am working on a 46 Chevy Suburban, the frame is missing many many parts, but have found a restored 48/53 with engine and everything...at a very fair price. Was wondering how much trouble it would be to swap to the newer frame ??? OR, if it can be done at all???? Any and All Help or Advice is much appreciated...Les in Minnesota
