I am just about finished with my 72 GMC C1500 build. It is a pro touring style truck. I have billett specialty 18"X 10" wheels for the rear and 17"X 8.5" for the front. Getting ideas on the drop and what size tires to run. I am considering a 2" front and a 4" rear drop with 255/55 tires for the front and rear. I don't want it slamed, just a good looking ride setting. Any suggestions? Thanks.
