Anyone have Iroc wheels on a bagged 71 or 72 truck?

I have a bagged 71 C10 and need to get wheels for it. I love the look of the Iroc wheels but they only come in a +10 offset size. I'm not sure if these will tuck on my truck because I read somewhere that the axle's on the 71 and 72 year trucks are wider. Just wanting to see any pics or get info from anyone who has them on a bagged 71 or 72 to see if they'll fit or if any mods will need to be done to make them fit.

Thanks

if you're talking about real IROC wheels off a camaro they won't fit your truck bolt pattern, yours are 5x5, passenger cars are 5x4.75 (except for some caprices)

No, I'm talking about the aftermarket Irocs they make that are 5x5 (5x127).

Jayschevy, knowing your current tire size, wheel backspacing and width, and fender clearance, and the specs on the combo you want to run you can make a pretty good estimate.

you may know already, so correct me if I'm wrong. "+10" offset would have to be 10mm positive offset. that means the wheel mounting surface is set IN 10mm (or basically 3/8") from wheel center. that puts the outside of the rim 3/8" closer to the fender relative to a wheel with no offset. most rims have some offset, even stock ones.

what do you have now and what are the specs on the combo you want to run?

I've always like those iroc wheels

All of the 20x8 IROCs I see online are zero offset?

Dino had them on his orange sub.
Also on the 55-59 board "Beverly" had a set also. He has switched them out now.

Actually that is backwards.
Postive offset moves the wheel in towards the frame.
Negative offset moves the wheel out towards the fender.

Ah, I see. Maybe a set of those up front and the +0 out back. Or a 20x9, which is supposedly made, but I haven't seen.
