Getting closer to being able to install an oil pressure gauge. Couldn't find a 1/2" 20 UNF banjo bolt but I had a 12 mm x 1.25 banjo bolt and the local hardware store had 1/2" 20 UNF nuts and bolts.

following this

that's about where I got stuck
Test fit on my parts engine. I think it'll work. The allen head machine screw holding the colant pipe bracket is the next battle. Several options. Make a new reducing bushing with less of the bolt head retained thereby reducing A. Swap the machine screw with a phillips pan head or similar with a lower profile (B). Reduce the banjo bolt hex dimensions C. Or a combination of all three. Alternatively I could find some other way to secure the coolant pipe.

I learned something today. Banjo fittings vary wildly in dimension for a given banjo bolt size.

So there will be a version 2. Pieces prepped:
