Default Shift **** Thread

What is the the thread size for a C3 manual trans shift ****? Does it have a recess for the reverse trigger?

Thanks
Tom

1/2"x18 , that diameter allows the reverse lockout move up

Corvette vendors say 9/16-18 thread size of the ****.
I'm confused.

Maybe I am confusing things.
I want to make a shift **** for a C3. What size tap do I use to thread the ****. I know the hole has to be somewhat bigger at the opening for clearance for the reverse lockout.

Thanks again
Tom

Here they show 1/2"x18, you don't have a die to confirm?

Thanks. I don't have a **** or a shifter to use. I am considering making a **** for a friend with a C3. I'm going to Carlisle tomorrow so I look there for something.

Thanks for your help and your patience.
