1) Where can I get a steel Rear bumper?
--Rock Lizard Fab is the only place
2) Any good aftermarket fender flares?
--no one makes any
3) Are parts on the KJ and JK able to be swapped with each other?
--No,not without modifications
4) Are IFP 930 Super Rally really worth the cash?
I'd skip HID's and look at LED's,much better lighting,legal,and will last 1000 times longer if you buy the quaility LED's.
