Early A833 4 speed linkage adjustment help

I would stick in a drill bit or hex key and align 1-4 and then go to Reverse. Unhook the reverse linkage and shift the transmission into reverse. Shift the shifter into reverse and adjust the linkage. That should be damn close.
Toolman, I did as you suggested. Worked pretty well, went into reverse fine, but when fast shifting into 2nd and 4th it would bang against the reverse lever, so I backed it off two turns and the banging went away. Reverse adjustment doesn't seem as finicky as 1-4.
