I've looked into the posi locks but like you referenced they said they don't work with GMT800. Good to know that they will actually work with these trucks. The way I have the new transfer case wired, I actually wired in a switch that opens the circuit when activated to allow 2wd low range. I have not had issues with the electric actuator yet but will definitely look into swapping to a posi-lock in the near future. After all the work I did to the 9.5" out of the obs I probably could have come close to breaking even $ wise on the 9.5" from a nbs (when time is factored in). I found some locally but they were wanting $1200-$1600 for them. And at that price point I was still looking at probably re-gearing, rebuilding and re-braking a newer axle anyway. I don't like putting new to me items on my truck without thoroughly going through them first so I can "set it and forget it" Given I only paid $250 for the axle I have, I was a lot of $ ahead even with the extra work. Frustrating as it was, it was a great learning experience and could do it in probably 1/3 the time and headache if I were to do it again.
I love the way those Level 8s look with my truck. It's a different look that you don't see with everyone elses truck. My truck happens to be Paint code 929L "Cashmere" not exactly a manly truck name but it is one of my favorites. Also seems to be on the rarer side slightly different than the silverbirch and pewter. Have to have touchup paint custom mixed as it is not a color that is normally stocked in the touchup paint grab and go's.
