Charging problems 67 Barracuda

SO I checked the brush marking on the new alternator and guess what - even though it looks like virtually identical to the old one the field / ground brushes are reversed on the new. They are faint but there and frankly I did not know to look for them. Just hooked it up the same way. So maybe all I have to do is switch the green wire clip to the 9 o'clock "FLD" and the black to the 6 o'clock clip. Insatll a new VR and I should be good.

The car has a 340 punched to 417. O'Reilly's Auto parts shows a 35/46 AMp VR and a 60 Amp VR. Which is the correct one to install? The first replacement they did not give me a choice.

This should be my last question! Hopefully by Friday I can report back it's all good. Thank you for all the advice!!!

67dart I can't believe I missed the link first time through. Although reading and re-reading I was better able to pick up on it when I did open the link.
