hey guys, i have two GMC 2500's, one is a 72 2wd 4 speed with 350, the other is a 71 4x4 4 speed with 350 and danas front and rear. i am planning to build one of these trucks up into a lifted show truck but the 72 is only 2wd and the 71's body is beat up pretty bad. i dont know which i should do, swap the body from the 72 onto the 71's frame or swap the axles from the 71 into the 72. which would be easier?
