Please allow me to threadjack for a second. When I did my frame swap, I just left the round-tube type hitch that was on the new frame. It was in good shape, and no reason to fight those bolts.
My issue is that it does not have the little mount for the trailer plug that the OEM square tube hitch has. So I just left it hanging.
Can someone please tell me (or show me) what the roundtube hitch setup is for the trailer plug?
PS. I have a OEM square tube hitch like Mauzer's for sale off the old frame, but I won't ship it. You have to come get it. No hardware. Rust is not bad.
