Can anyone tell me what the thread size is on a rocker arm adjusting screw for an early Ford 6 cylinder with solid lifters (144 or 170). I found 2 different screws listed for a Ford and am not sure which one will work. I have an early 200 CI, but i believe the 144 or 170 CI are the same. Thanks
Never mind, I found one.
