What rims fit 2wd sonomas? Z28's? 4x4's? Hey guys. I'm looking to pick up some rims for my truck because my rallies are lookin a bit rough. There's a guy selling 15X7 rims off of a S10 Crewcab 4x4. I have a 92 2x4 sonoma, the bolt pattern is the same. But I'm wondering about the offset/backspace. Also I've seen a number of trucks with iroc or z28 rims on them and they look great and I can find some for $300ish with ruber. Do these just bolt right up? or is there a offset/backspace issue which i would need spacers for?
