Here's the one I took off the bed of my 41 1-1/2ton chevy,I cut the front frame horns off and took 3" channel and bolted it through the front spring hanger mounts the rivets had already been replaced with bolts,and rebolted the frame horns on the end of the 3"channel so I could mount the bumper back on.Not sure of how many lbs it is but it's big.
I tried to find information on it but not successful,it's has allstate stamped on it,it is a PTO winch,but right now I have it as a hand crank,More for looks than anything.Would really like to have a 9,000 or 10,000 electric winch.This is what I had at the time.
