Gauges dimensions

I find things at the airport for my cockpit everyday (garbage stuff) and today I found a square piece of aluminum with a hole cut out that looks about the right size for the gauges but was wondering if someone could give me actual dimensions for them... such as Bezel depth, width and height, and also diameter of the circle. The gauges being Altimeter, VVI (I know, not square), Airspeed, and if different, the RWR..

The other dimensions if someone knows are for the 4 "blocks" to the left of the HSI: Standby ADI, UHF repeater, Clock, and I think it's an AoA? Are those 4 built onto a single panel?

Thanks in advance!

The article "Fighter Plane MIP Design and Layout" in the November "Mike's Tips" column on MyCockpit.org lists a number of mil specs that have dimensions for instruments.
