Tyler Renner at Metaltech products has been making custom A-arms for all 250 and 500's for several years and has sold many sets on here. They are excellant quailty and I think are around $460 raw. He also makes extended swingarms. Here's his site, they aren't listed on there but he makes them. Just give him a call and have a set on your door step in a couple weeks. http://www.metaltechproducts.com/
