Decide to sell my blazer. Here's what it is. 1973 k5 1/2 ton axles. 4" Lift Blocks in back springs in front, 33" tires. SB400 th350 NP203 Runs and drives okay. Needs some body work front floor boards, rockers, hood, but in pretty good shape for a 73 full convert in Mic Good project for someone with more time than me! $1300 or best.
