I recently purchased a Model 7 backhoe with the associated hardware to mount on a 770 tractor. My tractor is an 855 and I am working on getting it mounted. Of course, none of the brackets are available so am looking to fabricate them locally. The important link is the short one that forms the link to the upper clevis of the 3-point hitch; the link is made of two parts that are pinned together. I need the distance between the two farthest holes of the aftmost link, the one that attaches to the upper point of the hoe.
