Hopefully, I will soon be buying a Bobcat 709 backhoe at auction for my 160S. My local Bobcat dealer wants $ 427.50 for a set of the brackets to mount the hoe to the cat. There are a couple of pairs of brackets on craigslist for a 763, and I've been told that the frames of the two units are the same...true? Will 763 brackets work on a S160? Failing that, is there a more reasonable dealer in regards to pricing that I should contact? Thanks
