I just recieved my 2nd ALTENATOR in 3weeks?I have a 79rx with 80 motor.I ordered one for a 79 and found out that it was designed diffrent and would not cinch tight enough for the belt to get tight.the one i got today is for a 80 bolted right on AND now the PROBLEM is it has a TWO plug connector and my ORIGNAL has a FOUR plug.IM asumining this might be because of A INTERNAL REGULATOR?Any way SINCE thers is onlyTWO WIRES that go in to the FOUR PLUG conne ctor (STOCK WAY) can ihook the TWO wires tothis NEW 2 /prong ALTENATOR i recieved today? im begging for a answer im getting pressure from land lord for working o n CARS at the APTS.. thanks
