Duncan Motor sports ratchet shifter ?

I had one in the Duster. I had problems with it jambin up
a couple times. The first time it stayed in low gear. Lucky
I was only a few blocks from home. The second time it would
not go into 1st or 2nd. Pulled it out the last time and put
the stock setup( another shifter) back in. I can still shift
it pretty good with the stock setup. It kept bending the
detent in the shifter asm.
