So I've got a leaky steering box and haven't found any rebuild kits and any thing I can find is for 9/72 and later, mine was built in March 72. Besides the leak, I've got a fair bit of play in the steering as well. Have the adjustment screw almost all the way in. Was looking to buy a rebuilt box and with the exception of one place, which has them listed pre March and post March, they have them listed pre 9/72 and post 9/72. Kind of lost on what to do and hoping for a nudge in the right direction
