Not sure how they size them, I have a set for the lower PR tube. They don't have any markings. I also have a set for the SE breather plate bolts. Will a measurement help?

I have the measurements for the push rods but not the breather bolts, just can't find my parts book to get the HD #'s

Equally important as the size, is what is the o-ring material, and the durometer.
