Just so I'm 100% clear on an 8 3/4 swap!!!

it was a slant 6 car. Does that mean i have to swap leaf springs as well? I was only only going to swap rears.

No, you don't have to swap the springs, but the slant 6 springs are softer than the v-8 ones... It would be a good idea to upgrade eventually....
