no offence, but this just isn't helpful. "I believe" and "something like" are terms that should not be used when trying to help somebody with wheel/tire fitment.
Here's what is confirmed, dead nuts true, and tried with success many times already:
1) 17x8 Mustang wheels from 1995 thru 2001 have 5.72" backspace and are the wheels of choice for this wheel/tire upgrade.
2) Later Mustang wheels (2002 and on) have deeper backspace, anything from 5.92" on up to well past 6.25" and would likely require big changes to a stock 1967 to 1975 A-body suspension to fit properly (unless you're OK with 1.5" plus spacers).`
3) .75" or 1.00" spacers are all that is needed for the `95 to `01 wheels to fit into the rear wheel well of an A-body properly, no spacers are needed if you use a B-body 8.75" rear end. Some people have said they needed spacers on the front as well. My personal experience with two different types of the mustang wheels hasn't resulted in the need for front spacers. 8.25" rear ends should use a 1" spacer minimum as that rear housing seems to be a bit narrower than a 8.75".
4) The Ford center register is too small to fit over Mopar hub (spindle nut housing), so either the hub will need to be turned down to fit the ford register size or you can hog out the register opening on the wheel.
5) It's possible the upper control arm zirk fitting might contact the inner part of the wheel. Simply change to a lower (90 degree) fitting to fix this.
best thing you can do is to take a straight edge and a tape measure with you and measure width and backspace on any wheels you look at.
I hope this helps, good luck! -pauly
