JDL,you have got a couple of oddball answers here and also some very helpful answers. What causes someone to give you an answer that is offbeat is that it is such a basic thing.I agree get a shop anual and start studying it.What you posted is the oil fill cap and it seems like just about anyone would know that.I for one think that it is great to see someone of your age with an interest in old trucks.But you left yourself wide open for that one.
