Rocker Arm Shaft End Cap Freeze Plugs
Guy looks like the primary source of Mopar SB rocker arm shaft end cap freeze plugs are no longer being produced. Mancini and Chrysler dealers are all out.
I found a working solution that I wanted to share with you all. It’s a 5/8 cap with roughly a .235” height. Can get anywhere as they are a Doorman part. Doorman 555-011
Hope this helps anyone in need.
