    Berkley 12JC-A vs. 12JC-A-1???!!! HELP!

    Can anyone tell me the difference?
    I have a 77 Winder with a 460 and has the 12JC-A, drop snoot, split bowl, wedge and diverter.

    On the other hand, I have a 74 Tahiti with the 455 and it has the 12JC-A-1.
    WHAT THE HELL IS THE DIFFERENCE?????

    My Winder is a project and my Tahiti is a runner. I thought of taking the goodies off the Winder and put on the Tahiti. Is that possible?
