Default Hurst => M20 mount

I got my hands on this Hurst shifter. It’s supposed to be for mounting to a Muncie M20 (69-70 I believe).
  • This only has three holes but there are five in the M20; is this yhe right mounting plate?
  • What size bolts do I use for the mount?
  • What are these curly clips called; what do I shop for?
  • I’ve watched a few YT vids… any recommendations?

M20 is just the option code. Is that a B&W Super T-10 perhaps? EDIT: Nope

In 80-81 C3s, Hurst shifters required a different adapter/mount/linkage kit. It is NOT made anymore, and rare. If that's what you need. I'm sure it can be adapted, though.

I can try to get a photo, if that's what you need. There's a Hurst shifter in my 80 with a Super T-10 4-speed.

You could also contact Long Shifters, and see if they have a solution for you on the shelf.

Sorry… it’s a 69-70 Muncie M20. Thanks, I’ll contact Long Shifters.

In that case, Hurst might still make the adaptor plate, if it is different than what you have. They might have instructions on their site, too.

I'd still contact Long, though.

They do. And if the OP doesn't have that tool, it's here. Only $3-! It must not be Corvette specific, or it would be $35- or so.

That does not appear to be the right shifter for a Corvette. Doesn't mean it can't work, but you'll be reinventing the wheel.
Here's the page from the Hurst catalog that gives you the right part numbers.
