If you love air tools, you should try a bigger compressor, thats when its real fun, and having 3 different tools feeding one compressor, thats the shit, a 5/8, a 9/16, on impacts and a ratchet.

That rear is a Ford 9" very desirable, however expensive as hell to modify, such as differential and brakes.

Good job, looks like you got alot of work done.
