Removing Axles on a 7.25"

So, I made a goof. Looks like the rear end is already 5x4.5" bolt pattern, I just must have measured it incorrectly. I was wondering why the rims already were hard to get a socket on; they have been slotted to fit the SBP in the front and the LBP in the back. Doh!

Off to eBay to order the rest of my front swap parts so I can get this bad boy on the road! Thanks for the help all!
