I purchased for a woods 7500 Backhoe I knew I would have to modify to fit according to other posts I had to widen the thumb and the thumb mounting bracket 1/4 inch to fit the Backhoe arm I also made a 15 inch long shim that is half inch thick at one end and three-quarter inch thick at far end to take up the space between the mounting bracket and the arm on the Backhoe also welded a couple of pieces of metal to keep shim from sliding out if it were to wiggle loose And made one new pin to go through from mounting bracket original was quarter inch too short at that point. The thumb works great as designed and I like that I did not have to drill holes in my boom or weld to it did not want anything permanent or to weaken for any reason. And I almost forgot the price shipped to me for less than $150 and received in approximately five days great service!
