Here's "Obadiah". It's a '86 GMC Sierra Classic. I finally got him dropped last week (All Belltech, 4/6 drop, Spindles, Coils, Shocks and Flip Kit). I have found some 22x9.5" wheels with tires on CL for a great price but after combing tons of threads and searching other sites, I'm still unsure of the proper backspacing, front and rear. Most of the threads were from the 67-72 guys (good insight, no doubt) but I would like to hear from the 73-87 Squares. Thanks for any and all help--Jay2Cor517
