It seems I wasn't clear about what I am searching for. Let me describe. The type of adjustable hitch I am looking for has four main parts, five if you count the ball. First the biggest, a L shaped stinger that has a series of closely spaced holes in the long part of the L. Second, two pins with clips to secure them which allow the ball mount to be moved up and down to adjust the height of the ball. And third, a ball mount that has two holes in the ears, or what ever you call them instead of ears which allow you to secure the mount with the pins at the height selected. All I am looking for is the moveable ball mount.
The key factor of the ball mount is distance between the ears so as to fit the Reese stinger and the spacing of the holes in the mount so as to match up with the one inch center to center spacing of the holes in the stinger. The holes in the stinger at first glance seem to be on one inch centers but looking closer appear to be on 15/16 centers. The holes are 3/4 inch. The distance between the ears would need to fit a two inch stinger drop arm.
I think I have already looked at most of the suggested items but looked again. So my next move is to email etrailer for the dimensions of the one item they carry that looks like it will work. Once again I am not looking for a mount with load bar holes, just one that will mount a two inch ball. I am just pulling a 20 foot boat but when I unload the TC the bed height changes quite a bit and I have to change out to a deeper drop stinger, extra thing to remember to carry and use.
Yes I could just purchase a complete unit but I already have the Reese stinger which stays one the truck to limit rear truck damage from a distracted damage. And hopefully cause severe damage to the offending vehicle.
The last thing is the Reese stinger number, 54917.
Edit: it appears that Hidden Hitch part number 80418 might work, depends on the small difference in pin hole center to center dimension. A phone call is in order.
