Need help with gauges PLEASE!!!!

Guys,
I put all my dash back together and installed in the car (67 barracuda). Every thing works eg indicators, lights, etc except I'm having problems with the fuel gauge and temp gauge. When you turn the ign on the fuel gauge was going right up near full with no fuel in the tank. I went to try the temp gauge to see if it was working (no motor in car yet) and put the sender unit wire on the old sender unit, earthed it to body, turned the ign on and the gauge goes all the way to hot?

This is where the **** happened...while playing around with the ign on, the temp sender wire must have earthed out (didn't see it) and smoke started coming out of the gauge cluster behind the plastic bezel, not sure which one, could be fuel gauge? Since this happened the fuel gauge won't go above 1/4. I pulled the wire off quick, don't know if I saved it or not?

Questions? Have I smoked the fuel gauge/temp gauge?. Is there are voltage reg that may have burned out? any ideas what the problems could be with both gauges. Need to get the car done ASAP for summer down under. If I have stuffed the gauges can anyone help out with a couple of good secondhand ones?

Help much appreciated

Regards
Dave
