Yah pics of the top bolt pattern would help, not the ring gear side, the other side. the detroit true trac has 3 bolts on that side, and helical cut side gears that you can see from some of the holes in the side. I hate the truetrac and have ran them in 2 different axles in the past 7 years. I would go lunchbox+open carrier or a full carrier grizzly or detroit. unless it works and it was free, then Id just do that.
found myself mashing the brakes too much to keep it locked, then trying to drive through the brakes. way not fun when you can just count on a locker being locked up front instead of the LSD , but that was just my experience. it depends on your wheeling. we are mostly rocks out here, where you will always have a front tire off the ground at some point, and thats when it wont lock, thats the only time i need it. If you are doing lots of loose hill climbs in the mud or dirt I would imagine it would far better due to the fact both tires will be firmly planted.
I know many have had great experiences.
