Okays, I have a 1985 Yamaha T80 with heavy rust to the back of the swing arm, and it's failed the MOT due to it. I need to know if the swing arm on a 1997 model will fit the same as the old 1985. the other option is to weld it, which is fun, but finding someone with equipment is proving difficult 
Thank you in advance!
