Hi Guys i bought a 95 rcsb z71 the other day and wondering if i can use the 2" factory rear lift blocks that were in my 02 Gmc Sierra ecsb z71 that i put a levelling kit in previously? I have them sitting here and wondered if anyone has tried or used them or should i buy a set of ready lift, etc rear blocks? I wanna do the torsion keys also to give it a bit more height. Thanks for any info guys...
