Hello I'm a newbie to this forum. I recently bought a track 2 to restore with my grandson. The rear wheel and shaft housing with the sprocket flange and brake drum flange is bent. This is a welded assembly, wheel to shaft and flanges to shaft. I have been looking for a replacement but can not find anything like what I have. It has a 4.00x8 tire. Any suggestions would be greatly appreciated. Thanks Oldguy33948
