Per the post below, here is how I installed 4 clutches on a 7000 front fold.  For the wings I had to have a 7/8 shaft input and 9/16 output.  I just turned the sprocket inside the original bracket and spaced it out with washers, then created another hanger out of angle iron.

Total install time was about 3 hours and didn't require anything but chopsaw and drill bits. Used weld-a-sprocket hub with set screw to hold all in place-thanks Il_no-till for that tip.
