size threads on the oil pressure switch

[Redsnake2]

Ok guys i'm at work and I have all AN-4 stuff for free (well not free) and I think the oil pressure switch is a 3/8 or 5/16 anybody know the diff?

The stock oil pressure sender should be 1/4" NPT (if that helps).

actually the oil sender is 3/8 npt, as well as the water temp sender in the manifold.

Are you sure? I have 1/4" threads in both stangs.

i thought i was positive both were 3/8 but i could be wrong.
