I bought this very sweet hitch on eBay thinking it would fit my W123 sedan. It is the original German factory hitch. I picked it up while on a busniess trip, I wrapped it, I got it on a plane, I paid the cabbie extra to bring it home....and it did not fit.
I believe that it will fit a wagon as the "legs" do not go around the spare tire, while the wagon has the tire on the side.
check it out, open to offers, located in Long Beach, CA
Yes, still have it. I have no issues measuring it, and will do it when I get home. What's your email? I am avaliable on Saturday only this weekend (April 5th) as i am travelling this weekend.
