A few years ago the local red store installed a JD 260 loader on a 10 or 1466 tractor. I do not believe they modified the mounts beyond bolt hole alignment. The loader was well worn in the pivot points and maybe helped them get by with the small difference in frame width. I know it left there on the tractor because I bought the independent joystick valve that was closed center and of course unusable with the red tractor. Hope this helps.
