YH Code wheels?

[Smartin72!]

Hey all, as I am going through documenting what I can on my Z28, I took some pictures of the wheel codes, which show "YH"... . Any way to tell whether these align with how they should look? Everything I have researched so far tells me they are correct, but I'd like to get some feedback from folks that have way more knowledge on these topics than I do...
