Pat died before we figured anything out.
Since my back hasn't been behaving for months (and probably never will), I've decided to sell my own HUMMWV Bogert jack -- it's too heavy for me to work with any longer. Instead, I'll avoid driving off-road, and go back to my hydraulic jacks and 2x8x16 blocking, with a hand full of cash if needed.
There's a socket on top of the Bogert jack, maybe about 1 1/4" in diameter and about an inch high, that I'd planned to weld up an adapter for to handle Pat's axles. In my own case, I planned to grab a bolt head like the HUMMWV application.
The military jack is definitely well made - an old friend of mine used to say "it just smells of money". Mine cost a bit more than some that are being sold on-line, but it had been stored indoors. It comes with a canvas carrying bag that any 18 year-old soldier could probably carry with one hand...... The PITA about buying one is shipping - it weighs about 75-80# in a box, so UPS gets a bit of $.
A jack in A-1 condition sells for about $400, plus shipping --- if you want to buy mine, $200 plus shipping. Plan B is I'll bring it to the off-road flea market.
I don't know if you've seen a manual for the jack, so I attached a copy.
