1969 chevy C20 pickup alternator problem

Hello, my 69 pickup had the old school external regulator on the old alternator and the regulator went bad and was charging at 15-16 volts. So i bought a one wire alternator and it is only charging at 12 volts which means its not working right? does the truck need to be re-wired to be able to work on a one wire internally regulated truck? Also, can i still get the old school external regulators? At autozone or advanced auto parts? cuz if the truck has to be re wired Id rather just try to get a new voltage regulator at autozone or advanced if possible.

I went through 4 alternators for my 1970 chevrolet 1/2 ton truck before I got one that actually worked. I bought from O'Reillys aka china parts depot.
