Its where the oil pressure switch screws in the timing side cover. I am not wanting to use this switch so I just want to plug the hole. Is it something like 1/8" NPT? Anyone know?

Cheers Dan.

The year of this engine is also 1971.

Fantastic, I found a seller to sell me a blank plug for this.

Thanks BadNewsDan.

Cheers Dan.

It's 1/8 British parallel pipe thread. If you thread an npt fitting in there the taper will crack the cover. Look next time your at a swap how many are cracked

Nope, its not that. I just bought a plug with that thread and it doesn't fit

Do you still have the original switch?

No never had it, otherwise I could have had it matched.

Cheers Dan.
