Hi All, I'm looking to put a bigger swing arm on my 1999 Evo. I have found one on Craigs for $100, but the seller doesn't know what bike it came off. How can I tell the difference from my Evo 99 swing arm to the newer bigger sizes? Can I just measure across it? What is that distance

Thanks for any help.

get the part #, measurements then ask the Factory. they are not all interchangeable
