Rob.. the diameter of the spindle where the seal rides, is 1 1/4" dia. However, the part that the bearings ride on, is 1" dia.
I stopped using those small spindles a short time after this thread was started. I purchased a lathe so I could make my own spindle tubes, and stepped up to the 1.375"dia (at the lower bearing) spindles (1.75" dia at the seal portion).

Slightly different tow bar setup on mine, but same clevis mounts, I believe (unless changed in last year?), but I used 7/8" shackles that fit very tight in there (actually had to clearance a couple thousandths to fit) so I can leave all the time as shackles, and use to hold tow system.
I always like dual use utilitarianism, and also occasionally use my GPF bumper(s) as a work surface or anvil.
Eddie made these for me (THANKS EDDIE !!) & I suspect he cut them out.
I also have 7/8 shackles and tried the screw pin idea. It worked but there was just a little play. The 1" clevis pin is nice and snug but allows smooth pivot with little play.
I think Eddie is on to something here. I'll post some progress pics a little later today of the rest of the set-up. I realize with these mounts, width (were the shackles are mounted) is not as important as it was with my last towbar. Truly universal, I could hook it up to many Jeeps with shackle mounts.
So I've probably received the best email from my wife today in quite a while... (normally emails consist of the typical "honey do" type list)
"Fedex stopped by today and left 2 ridiculously awkward and heavy pieces of metal sitting on the front step. WTF?"
In other words, that must mean the bumper and tire swing has arrived!! I can't wait to get home today and check it out then start prepping/painting to install it this weekend and grab a few pics of it all. I'll be sure to share some BESRK/Ground Pounder pictorial results as well as a little review.
I owe you an apology, because I waited so long to post my pictures. The truth is i got busy with life and haven't had a chance to post.
As a testimony to Eddie's bumpers, everything fit like a glove! Couldn't ask for a better fit or better durability. These are HEAVY and I wouldn't be afraid to hit a brick wall with these.
The only change I would make is that I would have them powder coated instead of painting them. Maybe in the fall, I'll pull them and have them blasted and powder coated.... Maybe..lol
Lastly, Eddie made me a skid plate for the steering box, but it hasn't made it's way on the Jeep yet, nor have the Rotopax holder, nor the Hi-Lift jack holders, but these two are because I haven't bought the rotopax can or the jack.
This is my first post since joining and finally made my way through all 130 pages. Your rear bumper and swing out has inspired me, now I have 20 feet of 2x4 tubing in the shop. You do great work. I was also impressed with the rear disc brackets I got feom you a few weeks ago.
