Preparing to install my new rocker shaft I find that a few of the rockers arms are a little more loose than others. Digging through my 35+ year old stash in the attic I found a rocker assembly with the self locking adjusters. The shafts show only slight wear, so I took them apart to check the rocker arms for wear. They look good, so I would like to use some of them on the new shaft. I took the self locking adjusting screw out and installed one with the lock nut and it seems to fit just fine. Both types look physically the same. Holding them side by side they are the same length, etc. I just want to make sure I'm not missing something and can mix/interchange the two types of rockers with no ill effects. Thank you for your continued patience with my questions.
