OK, I do have pics.
The jack is a smittybilt, which I do reccommend when you can get it for $40 to your door.
The bracket with the pin (bottom of jack) is a piece of 2" square tubing notched to hold the jack and welded to the bracket that my swing out ammo can mounts on. The top mount is a piece of 3-4" plate held to the bar with muffler clamps and has a grade 8 bolt thru the middle that is welded to the plate and drilled to accept the lock. The lock is key, my last jack was stolen along with everything else in my jeep.
