Those that have purchased GM water pump and opti o-rings seals
Did you notice that the o-rings were in colors?
I got some that one pair were blue and the other gold. They were both stuffed in one package so I don't know which are which.
They look to be the same size and that kinda surprised me. I guess I though they weren't. Anyway, who knows which color is water pump and which is opti? I guess it matters somehow. <shrug>

I guess that is why they cost more than the water pump o-rings.
That makes it easier to remember, lol!
