Hey I have 1990 C1500 2wd. currently with 15*10.5*31in tire wheel combo. Wanting to do a new set up. And plan on lowering the truck later on. I Was thinking about doing a 17in or 18in wheel, i was thinking torq thrust but I'm having trouble finding a place to get them. Anyone know where to look or know another good wheel for this body style. And does anybody know the stock bolt diameter is?
