I have a 1951 chevy 3/4 ton. i would like to make it into a short box 1/2 ton. how hard is it to cut the frame and splice it back together? i would like to just get a cheap half ton frame, but i can not find one anywhere around this area for a reasonable price. can anyone help me? i live in des moines, iowa, does anyone have a half ton frame they would sell? thank you, mike
