Rear end for 65 barracuda with 5x4.5 bolt pattern

Hey All!

My brother and I are attempting to restore a 65 barracuda. (Or first project car!) It was originally a 273 v8. It is not a commando. It did not come with an engine so we are putting a 360 v8 in it. We got a disc brake conversion for the front brakes that has the 5x4.5 bolt pattern on it.

So obviously we would like to have the back wheels match the 5x4.5 bolt pattern.

Also I think the existing rear end is not strong enough to hold up to the hp the 360 will put out?

Does anyone have any suggestions on the best bolt-on rear end solution?
8.25? 8.75? Ford 9in? Used? Aftermarket?

We are not looking to cut up anything and don't care if its original or not.

Thanks!

Scott
