Bill,
While it will work on the V8 engines, take note that the V6 starter is different internally. The 65 Skylark/Special Chassis service manual explains it. The windings in it are different such that it turns faster, but has less torque. I dug into this back in the early 90s when I converted a 65 Special from a V6 to a 300V8 4bbl engine. I used the V6 starter and noticed how it cranked differently than the other 300 engines I had with the correct V8 starter on them.
Alternator is the same as V8 cars though. The one you have should be a date coded original, which may be a treasure to someone here.
