fonz8261,

Please post the link that you are referring to.

I have no knowledge of the different paint colors and the years they were used (and, if there were differences between Chevrolet & GMC).

I had a hard time finding photos of examples of the different heaters/controls that had used the correct labels.

Also, GM might have used AIR (outside AIR, for 53-55 outside AIR control) instead of PULL TO CIRCULATE in some 53-55 years (or, maybe, there was a difference on GMCs).

If anyone has photos of any examples, please post the links or email/PM links/photos to me.

Thanks

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