I just picked up an altenator from o'reiley listed as a 70? amp altenator with the square back for a 75 duster. Don't matter witch one I ground does it? The one they listed for my car was 40 something amps and not in stock.

Also I was wondering, since the main wire runs through the amp meter before going to the battery (is that right?)would it be a good up grade to run a wire straight from the back of the altenator straight to the pos. terminal on the battery? Are there any cheap easy upgrades like that?
