Agree but I am pretty sure the 3727s didn't arrive until the 73 model year. I have seen 2137s on 72 Olds' and those were gold. Also, in my pic above the Buick one is a spring 71 date and was painted black. Putting this all of this data together I am deducing a bit that there was consistency across makes as this is just how the supplier produced them.
What I don't get is why there are so many different numbers that seem to be the same unit, 80lb with 1/8 NPT. The one I currently have on my TA is another number different than these. Works perfect, looks correct and unless you are hanging over my passenger fender, you can't really read the number anyway.
