chris55.1,

sounds like a winner chris, i don't know about the later years, but i installed a 1981 caprice 10 bolt on my 51'half ton, just fine i'm using 10x15 rally's, chevy blt. pattern. ground down the axle smooth and welded new pads and two inch high blocks for a little lower stance.

never bottoms out, used 69 camaro shocks to keep it level, nice set up no regrets. good luck. jake
