I know it is more geared toward the K series, but it is the best one I have found regarding good info on RPO codes for 1972 trucks. Again I don’t know source of info so take it for what it is, but I am going with it being solid info.
According to the article, RPO code ZW4 is a Muncie SM330 3-speed. That info is about half way down the page. |
Correct, but as you said this is for 4WD's. I have been looking into this because there is very little info on the 330's. That tranny came behind every engine 4x4 unless the SPID says otherwise. It also came behind BB cars.
With that being said, SPID is bare when it comes to tranny and its a 2WD. So it would have been the Saginaw.
