I bought a 1 7/8 Proto socket at Pacific Industrial and modified it to turn the 5th gear retention nut.
I then boared out the socket to acomadate the 5th gear retention nut.
I drilled and tapped 3 holes coresponding to 3 glad lands on the 5th gear retention nut. We found a custom socket from a long forgotten project and cut off the 3/4 inch drive hole. This was welded onto the modified Proto socket.
