competition plus shifter

Looks like you have a 64-65 A Body Hurst Shifter. If you remove it and clean it up it should say "Competition Plus" on the housing. You can replace the housing and get the stop bolts if that is what you are looking for. Or go through and rebuild it, if you want to do that. Is it comfortable as is? You don't need anything new, for sure. I'd get rid of those cotter keys and get the right clips for the linkage. Those are great shifters in good condition.
