No idea. My post was more about recommending Mechman as a supplier than a specific offering of theirs. They make alternators for pretty much all makes and models. The alternators I bought from them made more amperage at idle than the factory alt made period, and fit in the factory location. If the alternator you want to use came on a GM from the factory, they probably make a high amperage version of it.
