Technical 1937 gauges oil pressure fitting

Getting ready to instal my gauges in the truck. On the backnof the gauge it takes a special fitting that i can only find in a 3/16 size line and i would like a 1/8, so iI can work with it easier. Does anyone know where to get one with a 1/8 inch hole.

 

The 1/8" version was used on Chevys...

you're welcome. I'm pretty sure I've bought them at the local parts store.
