7.25 to 8.25 Swap Questions

Hey guys, so I'm picking up an 8.25 rear end this weekend! It should be more than sufficient to handle the 350 HP my 360 swap will be putting out. I'm upgrading from the stock 7.25 SBP to 8.25 BBP. I put in the effort to find a rear end from another A body, so my assumption is that this will be a fairly simple swap as everything should just bolt right up (expect the drive-shaft) , am I wrong about this?

Also, the 8.25 doesn't have leafs attached to it, will I be able to simply use the leafs from my 7.25? Your help is appreciated!
