I have never run one... I opted for a mini-spool from the get go on this little rig
When I bought a set of 5.62 3rd's the rear had a lockright installed (with one pin through the locker) it had obiously been run that way..
SO, when I pull my 5.12's (which are in fine shape by the way) I am going to pull the mini-spool out and put it in my 5.62's... and then I was going to install the lockrite in the 5.12 rear, and sell them as a set..... worth more that way..
So many people wanted either the locker, or the front, or the rear... that I decided the easiest way was to just put them on the bay, and let the high bidder win, fair for everyone.. The last set of 5.12's that came with a locker (not installed) went well over $400.00... so I am expecting somewhere between $300-425 out of them on the Bay, with the locker installed, or at least included.. I still have the original spiders and side gears too...
My first objective is to get my 5.62's set up and installed.. but once I get around to selling the 5.12's all they will need is the backlash and carrier bearing preload set... the pinion depth and pinion bearing preload will still be fine.. hell, I might even install and set up the Lockrite.. it's really not that big a deal... but if it were me, I would check it anyway, so I assumed whoever bought the 3rd's would go over them before installing them anyway... (I would.....)
I will post on the "garage sale" forum when they are actually listed...
