Rodney,

It sounds like the regulator has failed in your alternator with integral regulator ... but it MAY have already done permanent damage to your tach or radio, too! BTW, the alternator warning lamp never coes on when the regulator is causing output Voltage to be way too high! The warning lamp only comes on when output Voltage is too low ...

What you need to know is what Voltage the alternator is putting out now, not the history of when it was most recently reolaced!

Get a multimeter, prepare a test cable to allow continuous monitoring of the 12 Volt accessory socket, and give us some data ... Voltage at idle, 2000 rpm, 3000 rpm, 4000 rpm, etc., or your best estimate of rpm, if you don't have a dwell-tach.
