Just like the title my idle adjustment screw on the intake mani is gone, missing, and i can only guess was super loose and fell out while i was test driving my car after recently rebuilding the motor, now it cant hold idle obviously this is no good,

searched all over and on google and catch seem to find the thread pitch and size for a good replacement screw at Ace hardware, i dont have any other iacv to get this screw from and dont want to go to a junk yard for one,
if anyone has a pic of the screw fully out so i can find something similar that would be great!
Please help soon, need to get fixed!
