Magnum rocker question.

I know there is a 5/16 to 3/8 conversion stud available, but that just seems like a failure looking for a place to happen.
I wouldn't worry, Oldsmobiles use 'em, i've got a 455 out there runnin' on the street w/over .600" lift & Harland Sharps 1.6 rockers. Been together since '07, they're built
to do what You need them for...............
