LOL! (as long as the driver of the cavalier wasn't hurt) Do body lifts require different shocks, or any engine bay parts relocation?  

With a body lift you are gonna have to drop some hoses, cables, fanshroud, etc. ut you keep all your same susp components including shocks.

If you buy a good kit, ie performance accessories 3" body lift, the instructions cover every little cable and adjustment you have to make. Comes with all the little drop brackets too.

My buddy put a 3" Perf acc body lift in his 88 k1500. took a weekend. We cranked the t-bars an inch and trimmed the bumper and he runs 35x14.5x15 (thornbirds actually) with only a slight rub, but he runs a prett sick offset on his rims (3"BS...about 8" of tire outside the wheel well). 

His truck looks pretty slick and does well off road cosidering there is no susp lift. The t-birds arent great though.
