Thee were a few good aftermarket shifters. Speco to name one. Jack, you can buy a new shifter from Rares.

Remember Jack Brabham and Stirling Moss in the Blues Union A9X 4 door getting hit up the bum on the start line? 1977 I think it was. This is what happened to that car I was told, as it was a road car with an M21 in it ie it got stuck in reverse on the start line!
