TeW = Just to clarify, your previous posts were all about a 1937 GMC T14A. Is this a new addition to your stable, or are we still talking about the '37 GMC with a Chevy 216 transplant engine?
Otto's info is probably mostly correct, but is dependent on what your truck actually has for equipment (including any upgrades or changes from original equipment).
Let us know more details so we can better offer accurate advice.
