Will alternator from M939a1 fit M939A2?

[Noah]

I am curious what the variations are between an alternator that is on a M939a1 NHC250 versus a M939a2 8.3l turbo. Can they be used interchangeably with small mods?

Is it just a matter of using different pullies? Or is it mounting bolts as well?

Thanks for the help.

If it's the standard 60a model then just the pulley is different.

Audible sigh of relief. Thanks Suprman.

Do yourself a favor and get a civilian alternator and bracket from 74m35a2 on here unless you are going for a Museum class restoration. You will be way ahead. the stock 60 amp is a pig.

Those are gang symbols of the big $ club. Not for the faint of heart, they are 3600 watt generators (28v x 130a).
