    Hey JW, checking one more time, are those rockers still holding up?

    Hey Jim, any update?
    I see you are wanting these early rockers now.

    If you decide to go roller cam, get Johnson roller lifters, NOT Morels.

    Yes guys, no issues with the 68-9 rockers... just make sure you use the hybrid pushrods.

    3/8" diameter ball on top to match the cup in the old rocker arms, 5/16" on the bottom to match the 1970 & up lifters.
