Well, since you asked, on several threads, it sounds like trouble to me. I am curious how an atomic 4 found it's way onto an 89 catalina 25. Sounds unusual?
As far as I know Universal stopped manufacturing the Atomic 4 in 84. It's entirely possible catalina had a skid of Atomic 4s sitting around, but by 89 who would have wanted one?I have NO CLUE... ( some may say obviously )
