Just trying to get a feel. I have the opportunity to buy a setup at a very economical price....... but I'm afraid the backspace may be way off. I just want the skinny on minimum and maximums ever used on this body style.... I really want to make the purchase for some forged wheels but I don't want to be out $500+sh if they don't fit.

Post the wheel specs on what your getting a deal on and we can help figure out if they fit. I'm running 17x11 on the back of my 65 with 6"bs and 17x8 on front with 4.5"bs. On the back to fit I trimmed the quarter lip off and replace the outer wheel well straight out to the quarter.

Well, I didn't mention the fitment because I figured I'd get alot of negative reaction to the fitment that would of course digress from the core topic.

What I have found are some never mounted, never had tires mounted rotary/cold forged 22x9 front 6.5" backspace and 22x9 rear 5.5" backspace. I wanted to run 255/30/22 front and 265/35/22 rear tires.

I now currently have 225/50/18 on 18x8/5"bs and 225/60/18 on 18x8/4.75"bs so I don't think the 28 and 29.3" diameters will cause much of a problem. The problem is the backspace and total width. I just wanted to know what maximums I could fit without any major problems. Currently my fronts rub the outter fender lip (bent the OE stainless trim already) quite regularly when driving through dips/driveways and over railroad tracks.

The 22x9's I've found would move the tire inward .5" from the inner lip and 1.5" from the fitment now. I guess on the 6.5"bs I was worried about Aarm/tie-rod clearance and on the back, I was wondering about 5.5" being too much as the 4.75" now is pretty close the inner wall of the wheel well out back.
