Brakes Dragging - Pushrod too long?

I have the correct original bolts and nuts with the pushrods. The bolt is a shoulder bolt for a reason and has a rubber o-ring in the center to prevent rattle. As the nut should be a top lock not a nyloc nut .


I have that same setup as well, but the shoulder bolt was too large of a diameter to fit in the new brake pedal I put in. Is there a different size for an auto vs manual trans setup?
