275/50R15's and 9 inch rear
Would it be possible to fit soem 275/50R15's on the back of my Cobra? I'm planning on relocating the springs inward like Robert Szewczyk did and trim the fender lips as much as possible. I want to go with Weld Pro Star XP's, should I go with 15 x 8" with a 3 1/2" backspacing, or 15 x 9" with a 5 1/2" backspacing?
Another question: I will be swapping a 9" rear under the Cobra when I do this, and I've heard a rear end from a 65/66 Mustang is the right width, the perches just need to be moved inward. Is this true? I've also heard a rear end from a 66-77 Bronco will work, too, it's just 1/2" wider (which could help me if I'm going with 5 1/2" backspacing), needs spring under perches, and the axles need to be swapped with ones with a 5 x 4 1/2" bolt pattern. Again, is this true? A big swap meet is coming in 2 months, and I will be on the lookout, and I have a lot of connections with Early Bronco guys.
