It's a "Buy it Now" auction, so I doubt this is banned here. Austin Weber has a rare set of M715 towbar feet there. Looks good condition, thought I'd point it out because they are hard as hen's teeth to find and I had a couple ask me about them in the past year.

I have a set myself, even though I no longer have the M725, mainly because I want a wrecker sometime in the future, and I want the full set of feet to use with everything.
