aftermarket guage dash pics/ideas HELP!!!!

This is in my Duster

That is exactly what I was looking for. I just could not for the life of me picture it in my head very well. What did you use for the guage hole templates? I just plan on a single large guage centered (tach) and two smaller sizes on each side stack one on top of the other but in a clocked outward position. So I can see them all simultaneously
