Outer Limits 4x4 Board

i have fitted a set of Crazy racing seats to the Mav, the seats are way too big on the "wings" and they hit the pillar i was just wondering the if anyone has had origanal seats retrimmed for better support, and did you get the seats covered in a different material like vinyl or something just wanted to be able to clean them easy and they OE seats get mud stuck right in there.
and just a rough price or contacts in melb s/e would be good.
cheers.
