I just sold one and it gets picked up this evening,I believe 68 to 75 will fit BUT in 73? 74? some inprovements were made to those units,they installed the indent spring and balls to keep it in gear better and notched the clutchdog to fit the detent balls.I kept an eye on ebay and got R gear F gear clutchdog and all the bushings for 200 dollars. Whats wrong with yours ? Popping out of gear? They have that problem and new is the only way to go! Buying a used lower may put you in the same place your in right now.Unless you can run the motor the lower is on and verify it good.
