Fitting for OilPressure Test Kit - 383

[LurkinLimey]

Hi Everybody,
Looking to buy an oil pressure test kit to baseline the oil pressure on my '68 383 stroker.
Any idea where I can get an adaptor to fit the oil pressure sender port at the top of the block?
Believe its NPT(?) tapered thread but don't know the size.
Any help appreciated!

1/8" NPT, eBay will have what you need.
