Frame repair Swing arm mounts

[sinned96]

Just wondering if anyone else had this problem The holes on the frame where my swing arm mounts on the left side are wallowed out. Causing the rear to move when I give it gas. Any ideas how to fix it? maybe weld some hardened washers to the frame with new bushings and longer bolts?

I had that on my friends polaris trailboss, I ended up upsizing the bolt and drilling out the bushing for the new diameter bolt.
Works like a charm now but was going to weld a plate on and redrill the hole before trying the new bolt.
