howdy Doug!
so what's the caper, lookin to set up a pto winch in something?
I'm thinkin might put you way ahead to salvage one out of another truck..
I found this guy a couple of years ago, was still around a year later, may still be??
it's a '70 Burb, by the looks of the SPID it was a GSA rig of some kind, maybe .mil issue..
anywho, it's a wreck, diff left open, interior rotted, etc. but I was only interested in the winch..
he wanted too much for me just for parts so I left it..
you may be able to find similar to suit your needs or I'll do some digging through my phone for a number if you're interested..
good luck!
