hitch handle fitting
Here is the hitch handle fitting I made. Not pretty but it sure works great. The fitting is a standard 3/4" coupler with a short bolt screwed into the top end, and secured with jb weld. I drilled out the bottom end to go over the stub that the handle was attached to. I think I had to grind off the rivet that held the handle to the stub. I drilled a hole through the side of the coupler to match the hole in the stub, and ran a short bolt through it to secure the fitting to the stub. The coupler is easy to find in a hardware store.
