I looked at the spare winch tube and it seems to be a PO mod. Just a piece of scrap tube welded poorly in place. Your still welcome to it though.
The crossmember and winch are also up for grabs if you or anyone else needs them. I'm going to take it out tomorrow and mock up a cardboard tank to be replicated in 3/16" aluminum and bolt up right where the crossmember is.
