teh part numbers are different, but whether it is due to minor changes, such as output shaft size, or form major differences rendering them incompatible I don't know. super A pto is the smae part number as 130 though.
The Super A through 140 PTOs are identical from anything I have seen. The A PTO came in early and late varieties. The early PTO had a different oiling system than the lates. The late one is mostly the same as the Super A but will not go directly on. The slider to engage the PTO does not work with the Super A transmission input shaft.
