3400 oil drain thread size

[Nick-G]

I'm looking to get a magnetic oil drain plug and I'm wondering what thread size I need. My engine is a 3400.

Also I will probably be epoxying a few magnets in my oil pan. What are some good magnets I could use?

Thats a 1995 beretta listing... I think all the threads were the same up to 04 3400's, I know the head size went from a 15mm to a 13mm nut somewhere in there.
