New gauges

[vht]

I've got a set of 2 5/8's gauges that I was going to mount under the dash. Manual, oil pressure, water temp, and volts all with a white face. My cluster has all the gauges along with a clock. I was going to keep them operational also, but have seen where some have installed aftermarket in the cluster. What do you all think on this, also what do you do about the printed circut deal and all of that? I was thinking if I did it, I've seen where you can get the stick on white face for the speedo and gas gauge. I don't really want them hanging below the dash, but I don't want to screw up my cluster either.
