I got the slider out and found out why. GM put an M21 slider with the locking groves for 4th gear in the M20 with High performance engine

Are you saying this slider was normally only used with hi-perf close ratio M21/M22 transmissions? I thought the locking feature was relatively common on ALL Muncies from the era.
