What color is the slant 6

I think the trucks 61-65 and some say early 66 got the yellow engine. My 64 Utiline has a yellow engine but, just a bit here and there. This is a near original yellow from a 65.

I think that yellow was called Primrose....IIRC.

We had the same colour here for the Dodge trucks.

One of the slants I have is an AT2 Dodge truck engine.
