fwd/rev shifter

So I've replaced the throttle cable on my hot foot, old one was too short so I added 2 feet and seems all is well. Now I'm thinking about replacing the side shifter. It's pretty old and rather loose and sloppy. Has anyone seen a side shifter for fwd/rev only, with or without safety kill switch? A short throw would be nice.

Just replace the original box and cable. Stay with one with a safety kill switch with the new law coming into effect September 01,2019 requiring you to wear it.
