El Camino help for Grandma, Cruise control

[4thgencreamsicle]

I know, I know, but it’s not mine! I’m trying to help my Grandma here! My brother is set to inherit our Grandpa’s El Camino (no idea what year) and the Cruise control lever is busted on it. She’d like to get it replaced before passing it on to him. My Grandpa was notorious for randomly parting things together so this lever could come from anything. Seeing if anyone here knows what it’s from and where I could get a replacement, even if it kinda spendy.
