Ok, my engine casting number is: 838941.
I looked it up and it is a 1939 engine...a 216.
I also found an ID tag on the firewall that was REALLY worn, but from what I could tell, it said:
Master 6
Car No. 21RD05 13785
Mike, hope the engine # can shed light on the placement of my vent tube. Any idea on the firewall tag #??
Thanks!!
