1974 Powerwagon 4spd transmission... how do I remove the shifter and relocate it?

If you have a New Process 435, the shifters on some of those had a cover you pull off, then twist a cap on there that's a sort of bayonet deal:

Don't remember the transfer case, I thought they were external linkage?
