Yeah that's pretty much the only ones I was finding. Might find the male to male and get my buddy to turn it down to fit inside a little.

Why? So you can even further needlessly reduce the id?

I got my an20 weld fittings from ebay. Just a little FYI for those going AN and using drive by wire. I ended up having to have mine cocked at a 45 degree angle coming out of the top of the water pump to be able to clear the throttle body actuator.

because I think it would make for a better welded joint and fit up. its not a rocket ship i'm sure 1/16'' isn't going to dramatically change my engine temp. I run a washer for reducer right now with no thermostat anyway so pretty much does all that in one step.
