Actually i just got done doing Both a 89 K2500 4x4 which was riveted for both ball joints and a 96 C1500 2wd which had the riveted upper ball joint and the pressin lower ball joint. I found the best way to get it done with out the appropriate tools was to air chisel the top of the rivets off and drill the rivets to almost half way through the control arm, and this makes is easier to finish off with a punch and a hammer or a air punch. FYI if your using the drill make sure your start with a smaller bit for a guide so don't mess up your control arm with the bigger bit and use something like WD40 for lubricant while drilling. Good thread so far wish i new about the PST group purchase prior to buying all new MOOG parts.

Also check the bushing size I ran in to 2 different size bushing for the upper control arms 1 was 41mm and the other was the 43mm. Might be a good thing to check with some calipers prior to ordering to be on the safe side.It is never a good feeling after you have done all the work getting them off and the parts store is closed and the new bushings are the wrong size.
