Info on Stant Safety Release Rad cap 18psi

[heywier427]

What one fits? Why is that info so difficult to find on the Internets.

Looking for a 18psi Stant Lev-r-vent / safety release cap.

Please only respond with, "this is the correct part # to buy".

Thanks.

No name s13 aluminum radiator.

Edit: Doesnt have to be stant, can be any of the safety/venting ones.
