I do not want to convert to a one wire alternator
Is there a 90 amp or 120 amp mopar alternator from a diplomat ot poice car i can use
need a serpentine though
Mid '70s squad cars used the 100a Leese-Neville alternator, but required special brackets and was never available with a serpentine pulley, just a double V belt.
Late '80s/early '90s had 90 & 120a Bosch and Denso alternators, some with V belt and some with ribbed. They also require their own brackets, or at least a modified bracket to mount the alternator higher- because of it's increased depth, it cannot be mounted in the "standard" location. Depending on your valve cover (assuming you have a small block) you may be able to mount it above the standard bracket, and relocate the adjusting arm to go above the alternator. I'll try to find my pics, but it's been a while...
How many ribs is your serpentine system?
With 7 groove pulley:
