If you know how to tie your shoes...... Parts, body and drive train are almost all swapable from 1960-1966. All fenders, hoods etc. (even though 60-61 had nostril hoods) Cabs did change though, 60-63 had a wrap around windshield, so that made the doors different also. Dashes also changed though out the years, but in general they are the same truck. Trim on "custom cab" trucks were different, chevys were more fancy while GMC trim was pritty plain. from 63 on Chev had a single head lamp while GMC had dual. The bigest differance and I still find alot of people who own these trucks and they don't know that from 63-66 Chev/GMC hoods were different how ever they bolt on to eack other. GMC hood, notice the signal lite and vent opening design... Chevy Hood, smaler uniform signal lites and different vent openings...
