My guess is you will be into something like this for the dash part.

Were there no directions with the speedo?
Wonder if you can download them from Autometer?

No I found it on the net somewhere.
I have been thinking on reworking my dash and almost liked the way that looked.

I see no tach was my problem with it.

That is close to how I plan on doing it, except put the pyro where the air vent would be, above the Tiny-Tach. No boost....yet, That'll go in the other vent.

Here's what I plan on it looking like, but I can change the background color if I want to. I dont have photoshop, so I had to do it on "Paint":

I haven't bought any gauges yet, they're my own christmas gift (you're never to old for gifts), I just wanted to plan ahead so installation is as smooth as possible.

That speedo is a 1:1 ratio (1000 rpm=60mph).
What is it in our trucks? Am I going to need a different cable / adapter?

Thanks

It has no air vents. Later on (I mean 10+ years down the road) if I want air vents, I'll move them to the A-pillar.

I can tell you that at 60 MPH with 4.10 gears on 235/85-16 tires your driveshaft is turning 2610 RPM.

Looks like you need an 8 tooth drive gear and a 21 tooth driven gear and it should read very close.
