Hey guys, real quick question here.

My 272 is clicking like all hell, I know it needs a valve adjustment, and what with this engine still running with unhardened valves I want to protect them as well as I can. I've purposely avoided going on any long trips because of this.

Problem is, my car has the older valve adjusters with the lock-nuts on them. I tried doing adjustments awhile back and couldn't do it. No matter how hard I held my screwdriver, the adjuster would always want to turn with the nut as it's tightened.. throwing off my adjustment. I know they had an old combination tool for working with these back in the day but I don't think they're around anymore.

A friend of mine on youtube Rpeek, sent me some of his old rocker arms, he has the newer type that are just really tight screws that you can adjust and be done with. Problem is he only gave me one rocker-arm worth so I need more of them and I'm not really sure where you can buy adjusters online. Maybe some of you guys have some you aren't using?

Though my main question is, will the non-locknut type adjusters fit into my rocker arms that use the lock-nuts? They look like the exact same type of rocker arms.. but I'm not sure.
