30, 41, 46, 50 amp alternators? Yeah RIGHT

Interesting information on the alternator outputs. It begs the question for restoration. All the A bodies I see have yellow cap batteries but the lower amp units would have green caps. I wonder what is correct. Example my 71 Duster 340 has NO a/c and NO radio. Wouldn't it have green caps instead of yellow caps?

Can't answer about the cap colors, but whereas some instances we see higher rated alternators had to be paired with larger capacity batteries, that does not appear to be the case for '71. See the Salesman Pocket Guide and Dealer Data Books here

Some claims here that all '71 cars had green capped batteries (post 33).
