    Anyone know a part # for a 120 amp alt that will fit the 6.2 without mods?

    I :dunno: but I think you can use the right side alt from a m1008,m1009 or m1028 they are 100 amps I think and the only diff between them and the civil ones are that the ground is shielded from the alt chassie.:dunno:

    The app for mine was an 83 P30 Van with the 6.2. You have to unbot the 4 bolts on the alt housing and rotate the housing 90 degrees to get it to fit correctly.
