Rear Suspension Hunt

I recently got a 8.8" rear end for my 69 mustang, and i have a 500+ hp motor, to put everything on the street i need a good rear suspension set up. The classic leafs just aren't cuttin it. I have found a few four-link setups, and i'd like coil overs, just anything that can help me hook up as best as possible, anyone got any good places to look Or suggestions? I don't want to spend a hell of a lot of money, around $1000 seems pretty reasonable, but i am not unwilling to venture above that for somethin sweet...

Leafs work great with a little help. This is a much cheaper option and it works.
