Biggest rear wheels and tires

[mechanic190]

I am planning on doing a us car tool rear spring relocation to my 72 dart swinger. And I'm also gonna be narrowing an 8 3/4 from a c body. I have a matching set of 15" cragar super tricks for the car when I was planning on a back half, but have since changed directions and just gonna move the springs. The problem I am running into without moving the springs yet just by measuring is I should have about 15 inches of clearance between the frame and wheel well but I have 15 inch wide wheels. What is the next (cheapest) way of fitting them? Or anybody have a pair of 12s to trade?

You're probably not going to be able to get anything much bigger than 325's out back. That's what I have and it's tight. That's with 15X10 wheels. I have my Billet Specialties wheels (15X10 and 15X4) for sale in the tires and wheels section if you're interested. You can make them work with the backspacing since you are narrowing your rear already.
