Slapstick Handle Needed

Got a '72 Road Runner with a slapstick. The "T" shifter handle is worn out and the button does not work anymore. Anybody know if this is available anywhere.
The parts boy at the dealer got severely confused because I wasn't talking about a Neon!

I got a replacement of one of these years ago from jims auto parts (jimsautoparts.com) For my Dad's 71' Plymouth Satellite Sebring-Plus. Believe they're based in NH. They should have either the parts or the Whole new T-Handle. Believe they're about 60 bucks..not cheap...but worth it. Hope this helps!
