you might need to make a new face plate for the SWR style meter.

I don't know what your application is (maybe you're looking for 
traditional d'arsonval meters), but these days, a microprocessor driving 
a LCD matrix display might be easier.  If you can deal with bargraph or 
numeric displays, a $30 arduino would probably do the trick.. 10 bit ADC 
inputs are standard.
