Hurst Shifter Question for Duster

I tried to post my answer last night, but got shutdown by thunderstorm.
I'm no expert, but I believe that if you want to keep the push-in (bayonet), you'll likely need to find a used original gear selector.

Or drill out the bottom hole for the standard handle.

Best advice I can give is give Brewers a call http://www.brewersperformance.com/, the guys are very helpful, and their in Ohio.

Good luck.
