i hav a 70 chevelle, 100% stock, with drums all around, now ive seem many chevells with camaro iroc rims, will the striaght bolt up or will i need spacers etc. all help apprcieated thanks!

The bolt pattern is the same but depending on the offset you will need some spacers. No positive answer, it depends on which wheels you get.

If you buy the aftermarket IROC wheels that are shown in chrome in most mags I believe you need 4 fronts to get the correct offset to fit a Chevelle. The rears have to much backspace. You might look in the wheel tire forum as this question has been asked before a few times.

here is a result for a quick search:

I bought a set of Chromed 18x8 Iroc wheels for my 87 Iroc.
I tried them on my Chevelle and they fit fine. I also have the original Iroc wheels from the car as well, but I never tried them on the Chevelle.
You've got me curious now....I may have too try those on the Chevelle and see how they fit. :)

I have heard too that you need to use two pairs of fronts because of the back spacing.

I have iroc front/rear setup on my 70 elcamino and they fit perfectly with 255/50's.They look good too.

Please remember before posting they will work that there are dozens of different "IROC" wheel sizes and backspacings. That doesn't even include the many aftermarket applications out there. I'd hate to imagine somebody out there cussing they spent all their "fun" money on a set wheels that don't fit.

A set of stock 88 iroc's with the 3 bar spoke design fit perfectly on my 70 elcamino.They are 16 inch with the ones labeled front on the front and the ones labeled rear on the rear.There are only 4 different factory iroc wheels including the 15 inch ones.
