now that i looked at them, they both are, which is fantastic! but on a side note, the "W" was very difficult to read, i was looking at a third alternator i had laying around, and i saw it said W beside an open square, so i looked at the same spot on the alternator not in my car, and of course it had a little terminal, and i looked again in that spot on my car, which is where the terminal is with the big plastic connector around it.
