Got it all assembled today, did a final test fit.
Will have to got to the HW store to get the vinyl covered clamps to mount it, as well as the hitch pins. I'm going to cut the head off the hitch bolt and drill for the pins. Needs to be quick attach & remove, an improvement over the last one with the double nuts arrangement.
Next step will be modifying the trailer to fit with the centered hitch. Will start on that tomorrow, after the final install of the hitch. will post pics of the completed unit.
I am also wanting to put mudguards on the bike, as I am out in all weather with my deliveries. I'll post those pics in a new thread.
