Rb25 intake manifold help!

[AutoRb]

Alright guys, I recently bought an freddy intake manifold for my rb25. Its pretty much prepped and ready to go on but im stuck on the hose nipples. I bought the manifold locally so nothing came with it and I cant find them anywhere. Ive been to about 3 hardware stores and vatozone and nobody carries the size that I need (I dont know if they are even made). I found the thread size but its metric and I dont think nipples are made in metric sizes.


These are the holes for the nipples. I need four of them




This is what im looking for


If you have used this manifold before, I just need to know the thread size of the nipples and where you got them from.
Ive searched and cannot find anything on it.

Also, I know i can just drill a slightly bigger hole and tap it to the size I want but that my last resort.

I know this should be in the RB section I just thought there is more traffic in gen chat.

Thanks in advance for any help!
