My 54/55 GMC COE dash looks like vwlfan's, including the knobs.

vwlfan's dash

Here is a GMC illustration with different style knobs.

Sam (GMCpanel) do you have a photo of your dash (I think I saw it posted somewhere, but I do not remember where).

Thanks,

The 216 and early 235 engines are not "splash oilers" -- this is a splash oiler.
