Cowl gauge mounting

Hey guys, just wondering how you all are mounting gauges on the cowls or outside of your cars? I've seen the way by bending a vent grill bar up and using that, but i would rather not go that route.

Any ways that i've been missing?

We used a small piece of sheet aluminum,bent so that the gauge sits on the metal and bent a lip so that it attaches between the cowl and the hood.The lip attaches where the washer hoses normally ran.We also used a steel line for the gauge and ran it thru the nozzle hole,and between the vent bar.No bending necessary!!

Thanks that seems like it should be pretty easy to do.
