Does anyone know of the company that makes an NHRA-legal replacement detent that provides a positive reverse lockout for the '68 horseshoe shifter? I've seen these things in the past but can't remember who made (or makes) them. I want to use the console and shifter, but don't want to get kicked off the track when some overzealous, officious tech geek decides my car isn't legal because of the lack of a lockout. Any help would be greatly appreciated. Thanks, guys.
