Danny, in our build thread I purchased a NOS yellow Delco eye and then we matched that paint to paint the caps that came with our Y55 in the early 80's as they were red.
Could send you a close up picture to at least come close on the color if you decide to paint some caps.
Premium Consumer product companies are VERY ANAL about their colors and they will not vary by much if at all.
Aint that the truth. Commonwealth Bank yellow is a single point on the HSL curve. And the most anal of all are the wine label crowd!! Just of the rails!! [I service the print industry]
