Yeah, I'm not really sure man. I looked into it and I seem to keep seeing different information. I see P/N's discontinued and superseded. Some thermostats with that gasket, some without. I'm certain I ordered Motorcraft parts. Hell, I stared at the set-up for a good bit before install trying to make sense of it. Then
still installed it wrong, before coming up with a way that makes sense in my head to keep it from leaking. I'm gonna take another peak. Seems like for the price of just ordering that gasket, I can have one of those MotoRad pieces. I may go that route or may just roll the dice with what I've got. Won't be a big deal to change out if I have an issue. Perhaps our good buddy
@FordTechOne might be able to shed some light here. Appreciate you looking out though brother!
