Adjustable rockers adjusters problem?..

I do think I have it figured out.. it seems as I got the 3/8 x 24 threaded adjusters with a 3/8 ball.. it looks like I need the 3/8 by 24 with the 5/16 ball. Probably need to run a tap through my rockers to get the pinch out of them...
I think the 3/8 x 24 5/16 ball are out of stock... Probably why I didn't see them...
