1970 Duster regulator and resistor

were did you buy your alternator and which one (size, amps?) are there any instruction out there on how to do this! I do have Mallory ignition on my 360 already!
I wouldn't run any mopar ignition or factory style alternator in any of my mopars. Been there, done that. HEI or MSD and a single wire alternator. Clean and effective
