Its not easy to make new brakets because of the CAT hump. DO NOT TRY TO REMOVE THE HUMP YOU WILL RENDER THE CHASSI USLESS...but I know you are smarter than that, so I would cap it or anything. Your best bet is to get a pair of the Bride seat rails (expensive yes, just suck it up) they will bolt into my after market seats that mount to the bottom, so you might have to think of a smart way to do that, but it is your best bet, otherwise your seat will be to high and your head will hit the cealing, unless your like 5 foot 5 like me!
