Hey guys, I'm here to see about getting a specific part for a 84 Yamaha YTM200EL. I've tried many online stores and they say that many of the parts has been discontinued (naturally).

Here's what's broken and needs to be replaced...



The arrow is pointing at the part that's broken...



Now does anyone know how to get this fixed or replaced? I may also consider getting a whole new rear end if the $ is right. The thing is, the bike is in great condition and runs fantastic, it's just this part that's broken. I guess stuff like this is bound to happen when a 16 year old thinks the bike is invincible...
