Well, I couldn't pass it up. $60 and less than an hour drive.
At worst I can use it for parts. Supposedly is was rebuilt between 3-5k miles ago and was built with quadrtrac parts (at least chain, I don't know about this upgrade/mod to know what all is involved).
It seemed ok as far as I could tell. I could shift it and it functioned as expected. I couldn't do anything to make chain slap or anything. Input and front/read output didn't have any wobble or feel loose, etc. Everything spun smooth. When in 4WD, if rotated the front output back and forth quickly, there was some 'slop', don't know if that is normal, but only thing that seemed possibly a miss.
Also came with linkage/bracket/shifter/boot. Shifter is extended one as it came from a jeep with body lift.
