In good used condition, the PTO is complete. The case has been welded at some time in the past, as can be seen in one of the photos, but it is leak free and solid. I used this for many years and took it out twenty years ago. Then the seals and bearings were fine. It is missing three of the five cap screws that attach it to the rear of the transfer case. I imagine Herm the Overdrive Guy has these.
$350. I am in Oakland, CA, but can ship.
