I have a 1954 1/2 Chevy panel truck no motor or Trans or rear end or springs . I also have a 1980 Chevy 1/2 ton in good shape with an automatic that I perched as a donor . I have perched a mustang two front end kit. But could use it in a dif rent project. I have skills and a big shop. Should I keep the original frame or swap it out for all the chasses in the 1980? On anuther form I was toled that the later truck was to wide And I heard it moor than once. The 1980 truck fram is 34" wide. The 54 is 44"wide
