Toro 550

Hello everyone. I'm getting this interesting little Toro in return for resurrecting what I do believe is the worlds WORST Wheel Horse B-112. (It's BAD.) I cant find a whole lot of info on this thing in the first place, but it IS missing one key component.. the rear axle. It looks to me like a Peerless 7100 series. I'm missing one whole side of it. The differential in the pictures is from a Wheel Horse A-81, but I don't think I can make it fit.. would anyone know where I could find a axle like this? I've seen a guy who used a Huffy axle in one. ..Dunno what kind of Huffy though. I'd really like to make this thing work, its a very cool little machine. I imagine I could run it like a Go Cart.. but I think without a Diff it would overstress the frame.. its not very strong.
