AFTERMARKET GAUGES

Who here has made there own dash cluster with aftermarket gauges ? What gauges did you use ? What sizes ? Any pictures ? I am making my own cluster for my barracuda. I wanted to go with 5 in speedo & tach but i dont think they will work. To big. There is alot of 3 3/8 options out there but i think that will be to small. I think 4 in will just right. Not alot of options in 4 inch. The other 4 gauges will be around the 2 in size.
