rims, wheels, whatever catches their attn...

[AspecialZ]

Ok ladies and gentlemen, I have a good question that needs an almost exact answer, but my problem is that I can't make up my mind, this is my truck, and I want to go with a bigger tire/rim combo, 17 maybe 18 for looks, but the problem is, I don't know if they will fit without alot of problems. If anyone has an 73-87 stepside, I am looking for ideas, by the way I'm not wanting to tuck, just a larger custom wheel than 15's for looks and driving..thanks all!!!
