I'm in the process of a 300ex project. I'm bidding on an old 250 s-stroke, but the chain sprocket is on the right, unlike a stock 300. I know I can use an old ATC250r swingarm, but they're very rare and I think I can get an '02 Cannondale rear end for a resonable price. Can someone please do me a favor and measure the width of the swingarm at the pivot point (distance between the swingarm frame mounts)? Thanks for any help.

Mine's assembled so it is hard to measure in there but I took a tape and got approx. 7 1/2" hope that helps.
