I searched, but, if info is out there, it's well buried in the history of this site.
I just bought a 78 C15 step side. It's very drivable, but needs a lot of previously ignored details attended to.
One detail I want to tend is, my ZERO love for under dash gauges. I like keeping my eye on the road. Just like I don't like looking at my cell phone [for the same reason].
Too, I want a tachometer, but I want it where the monstrous (oversized) fuel gauge is. Right next to the speedo.
To these ends, I want to install a 2-16" fuel gauge to the cluster to the left of the wheel, in place of that big boy. However, it seems everyone wants absurd amounts to get there.
To get around absurdity, I need to figure out what will work, regarding the after-market, relatively inexpensive gauges. I need to figure out if I can just put my Fluke in ohm mode, check out a few readings and pick a unit that likes my sender. Said another way, I have my work cut out for me (finding out the tank sender resistances and the gauge wants).
I know some of you have made your own wheels and can save me a lot of re-inventing (chasing down the Detroit standards seems an endless circle).
SIDE NOTE: My entire dash will be replaced with my woodwork. Just as I did with my 69 C10 decades back. As such, imperfect fits are just part of the project (i.e., the holes made will be as easily made for the after-market gauge of choice as for an actual stock
