I am working on a trx 90 conversion , and Iam looking for a company that will build me a rear swing arm with a trx 250 style rear carrier so I will be able to run a disc brake in the rear.



I have already measured a 300ex ,250,banshee,and blaster swing arm and they are to wide at the front about 9 1/8 inches the stock trx 90 one is 8 7/16 inches. and I thought about narrowing up one of those but it will throw off the alignment of the rear carrier and the chain would rub the frame.
