To craigslister that put this stuff up for sale....why don't you just order the freaking part and prove the winch still works....you'll make more $$$ and more buyers will take a look at it.
Kind of like putting trucks up for sale that ''worked 6 months ago''' or needs a muffler, or needs a tune up....
Sorry, petpeeve of mine...
