Image of the alternator you want. It is a Delco and the voltage regulator harness plugs right in.

Even though it is a Delco, it is larger than your original. 144 millimeters in diameter versus 130.
It is not a "drop-in" replacement. I would try the Chevrolet parts counter to see if a "CS144" bracket is available for your chassis. This is by far the easiest way to do this conversion.
The hopped-up original size alternators are utter garbage -- don't give a **** whose brand. The CS-130 and CS130-D cannot be pumped up in amperage without losing what little amperage they developed at idle. Like trying to convert a Citroen 2CV into a dump truck.
You must add a wire from the battery stud to battery positive direct. Six AWG would be ideal. When I say MUST it does not mean perhaps. You WILL fry the factory fusible link if you don't.
The CS144 is a sane alternator design. Even measured at 30-amps output, it is longer living alternator than your original.
Best Of Fortune!
