Looking to add a Tachometer

[jricharc]

So I recently bought an '86 C10 that has had it's factory V6 replaced with a 350 from an early 80's Z28. It has the Saginaw 3 speed with the shifter moved to the floor and I would like to add a tachometer to the gauges.

I am thinking my best option would be to replace the current large gas gauge that is next to the speedo with the new tach and move a new gas gauge over where the blank spot is on the left side. Has anyone done this and can they recommend any specific gauges?

I have seen a bunch where folks have done the entire cluster but that's just not in the budget so I want to find something that looks somewhat factory if possible.
