Re: Anyone have a spare of these???
I think you will find that is particular to 83-84 fsj's. It was on an np type transfer case they called Quadratrak, but not the same as the 70's. I think an NP219. The knob on the bottom controls the vacuum axle disconnect, which jeep did away with in 85, because you could not shift on the fly, you had to be stopped for the axle to connect. A good source over at ifsja.org is Crazy_Jeepman, go to the message board and do a search. he's got tons of stuff. Also, I think this mounts on the lower dash, just to the right of the steering column, like by your right knee.
