Looking for info on building a Custom Guage Cluster

[GMCJOE]

Well, I eventually plan on building my own custom gauge cluster for my 69 GMC. The current one in the truck only has 3 gauges (speedometer, idiot gauge, and fuel gauge). Going to start building a new one up slowly. I am going to use a instrument panel that has the 4 gauges at the bottom and 3 at the top. The idiot gauge will be replaced with a Tach.

Any one got pictures of there custom gauge cluster build?

One of my biggest issue's is trying to find a aftermarket fuel gauge that is the same size a the factory. I want to keep them all the same brand or same look. Any help and suggestions are great.
