RPO M20 doesn't mean &quot;Muncie&quot;. As far as I know, it was just the RPO code for &quot;4-speed (wide ratio)&quot;. GM decided what trans to use based on the engine. In this case, it probably is a saginaw. </div></div>

I would agree with this perspective...many Nova build sheets list M-20...that merely told the Fisher Body boys they needed to cut a hole in the floor for a manual tranny...not sure if this carries over to Chevelle docs...but, I can tell you that one of my hotrod buddies from back in the day had a similar car and it had a Saginaw &quot;iron case gear selector&quot;...you guys can take it from there.
