340 adjustable LOCKING rocker arm kit

Thanks for the photo. Those look like stock rockers and the adjusters I posted a link to above (from Napa) are what you have. I see you have a bent pushrod. You have more issues than a replacement adjuster.

I am moving this thread to a different forum and will re-post the discussion. You have some bad going on there. That photo you just posted could have changed the direction of this thread. Just sayin.
Which forum did you move it to?
