Rear tires not centered in wheel well

I recently installed an 8 3/4 from a 68 Satellite 2 door and my rear tires are way to far forward. I have about 1.5-2 inches in the rear but about 1/4 in the front. I reused the /6 rear springs could that be why. I also understand that my tires are really tall but I would think that I should still have a little bit more clearance. I will post pics when I get home form work.

As long as you are using the same car leaf springs, the rearend has nothing to do with the front to rear location of the rear. I assume you have an A-body? If so as long as you use A-body leaf springs, the location of the rear will not change with the 8 3/4. The B body rear is a little wider,3 ", but that is it.
