64 Barracuda rear end

Any suggestions for a 8.25" or a 8.75" rear end swap for my Barracuda? I just replaced the stock 273 motor for a 318 and i want to replace the 7.25" rear end that is in the car now.
Just so you know; on the street, the 7.25 is strong enough for the 318, so long as you don't spin just one tire, and do NOT do neutral-drops or J-hooks.
