hey guys I have a 1980 Toyota pick up 20R I’m looking for this bolt, it’s the Throttle body hollow screw that is screwed in through the bottom of the carb. Anyone have or or know where I can get one?

I hope that link works. I dont know if it helps seeing as the screw I think youre referring to is unlabeled.
The pic is direct from the FSM. It looks like that screw doesnt control anything but Im far from a carb expert.
is it hollow all the way thru?

Sorry for the long link. In the last pic is it the screw that goes up between the two butterfly valves?
