just got me a '67 Barracuda

So, I'm a bit naive to the whole rear end swap. I know that I'd like to have higher performance equipment on my car. It currently has the 7.25 inch rear end. All engine and transmission related issues aside, I'm just wondering what it takes to replace the rear end with a 8.75 inch pumpkin? Do I change out the leaf springs, too? What about my wheels; they are currently the 4-inch lug pattern. Will that change with new axles on a 8.75 rear end?

I'm just making a shopping/laundry list at this point.

Thanks!

You`ll have to find the housing with it`s backing plates, axles ,shockplates with u-bolts, 3rd member and a driveshaft. It`s not that much work, your best bet is to find a donor car in the boneyard that you can harvest the parts from for the swap. If I were you I`d simply drive the wheels off that great little car.
