geunther said:I went to a local farm and ranch suppy. But any trailer/rv/camping supply store should have what you need. Maybe even a welding shop that builds hitches. They should sell just the receiver (reinforced square portion) You will probably have to drill a vertical hole on the opposite end of the reinforcement and horizontal hole, for wich to bolt to the ssr hitch.
I will try and get you a picture.
Of course it wont be strong enough to pull a trailer, but will handle a few bikes or one of those storage racks.
