A Full Size Jeep technician told me that this assembly (photo that Nail provided) isn't heavy-duty enough. He had them in stock, but he didn't recommend them for my application because they aren't cross listed for any Jeep year below 1973.
So, I broke down (insert happy sobbing here) and bought the one in Greece. The entire assembly NOS (upper shaft plus complete coupler assembly) was $230.68 and that includes shipping. I asked for a tracking # and I used PayPal to pay for it.
I didn't think that was a bad price. It looks just just like the one in Dan's photo...all pretty in black. haha.
They have lotsa hard-to-find parts.
