You probably have already gotten your alternator? What I have is a Tuff stuff alternator that puts out amps at low RPM that fits right where the old one did with no problems. I'm running 2 fans that draw 37 amps electric pump at 10 amps. The new alternator is a 130 amps. Puts out 65 amps at 800 RPM and 85 amps at 1700 RPM. The tech I talked to said that for a Mopar that a regular alternator will put out higher amps at low RPM then a one wire. The alternator, electronic regulator and wiring harness delivered was $205.
