Where to get a rear-end

Hi all,

I have a 67 Dodge Dart GT Conv with 360 / 727...I still have the 7.25" rearend (just about shot) and I am in the market for a 8.25 or 8.75. I need the complete setup. With money being tight, I want to know if there suggestions on where to go for a used or refurbished rear?

Any info would be much appreciated! THANKS.
