Cleaning out garage to make way for Roadrunner on rotisserie.
Came across this in a box of parts from my Shelby Dodge days.
Does anyone recognize this? Is it a part from a 2.2, a special 2.2 adjustment tool, or a general purpose tool?

The bottom is flat, the hole is the root diameter of the threads, so nothing can come in from the bottom and thread into the inside threads.
