67 Barracuda 15x8 with 4" backspace?

[redlinegw]

Will these fit on a 67 Barracuda Front and Rear? http://www.summitracing.com/parts/CRR-3425812/ I have already converted the car to the large bolt pattern. I can also get these with a 4.75 back space. I would like to be able to rotate the tires.

Thanks,
