Guide plate stud
A gearbox guide plate stud used in the selector mechanism, part 21-0547.
This is the guide plate stud out of the gearbox, part number 21-0547. It shows up in the gearbox outer cover and the inner cover and selector mechanism drawings, which puts it right in the selector/gear-change works rather than out on the shell or cases.

Studs like this hold small fixed plates in place inside the gearbox internals, giving the selector mechanism a solid post to locate against. It's a small, plain piece of hardware, but if it's worn, bent, or missing the plate it's meant to hold can shift out of position.
Our records show this one appearing across gearbox catalog listings from the mid-to-late 1970s. We don't have dimension or thread specs on file for it, so if you're ordering to match an existing stud, best to check the physical part against what you're replacing before you commit.
Sorry if we got something wrong here. If you think this information isn't correct, .
