    Anyone know if 15x8 (rear) and 15x7 (front) wheels will work with a 71 GS when they have 3.75" backspacing? Looking to put Rat Rod Series 68 wheels on and they only come with 3.75" backspacing in those wheel sizes. I'm wondering if they'll hit the fender lip or wheel well (tires are 255/60 front and 275/60 rear)
    Thanks,
    Jhutch

    No they will not work. On a 15 X 8" wheel, minimum back space is 4 1/2". On a 15 X 7" wheel, 4 1/4" is stock.

    Just to follow up, if you contact US Wheel, they will make a set of their wheels for you with custom backspacing at no additional charge. Now that's customer service!

    Too bad they don't make Buick Rallye wheels.
