Have a 1293 on a 9120.    The top lip hooks nice. may have to widen the opening.  I had to notch the front lip on the feederhouse  for the center bearing on the 1293. Cut a couple notchs for the lock to hook.  Couple 540 shafts the right length.  Thinking JD 346 baler  front PTO shafts 6 spline one end, Hex on other.
