I am working on a 71 1614 basket case. I also have a 72 2414. I have noticed that the terminals on the regulator/rectifier are not labeled the same. They appear to be the same model regulator/rectifier though. On the 72 which is pretty original and running well the two AC terminals are side by side and about 5/8 from the mounting surface. The B+ terminal is about 3/16 from the mounting surface. The regulator/rectifier from the 71 basket case has the single, close to the mounting surface terminal labeled AC and one of the two other, 5/8 from the mounting surface terminals is labeled for the B+. I haven't seen other regulator/rectifiers labeled like this in looking at pictures on the internet. Anyone have any experience with this? Possibly mislabeled at the factory? Thanks for any information or opinions. Tom
