Just recently bought this car and nothing on the dash works except speedometer. Alt, Oil pressure, Fuel gauge. None of these work. Car starts and runs fine besides this flaw

I am not sure if the Mustang one works for the tbird. I'd caution checking the sensors themselves before replacing that.The 70s Fords have a special voltage regulator just for the dash instruments. After checking fuses you could look into that, although I don't know that would affect the alternator without having the schematic in front of me.

Is that power supply (regulator) behind the dash panel with the gauges? I ordered one and just got it todaySounds like the power supply (regulator). They are an electro-mechanical part so they do wear out. Their function is to open and close the voltage to the instruments so that it averages around 5-7 Volts I believe. They do this by heating up a bi-metal spring with contacts on it. Putting 12V on them will def peg them so I would not do that again.
I got one and will check it out. ThanksHonestly not sure where it is. Do you have the Ford repair manual on CD? If not, here's a link. I got one as soon as I bought my 70.
