Update. I decided not to rebuild the stock alternator and instead ordered a 145 amp alternator for a 97 Buick Riviera which also has the L67. Turns out DOES NOT FIT. Looks like they used a completely different body for the alternator. Different mounting points. I didnt think to check pictures on google images before making the decision to order it. Now I have two options. Either send it back and hopefully get a refund or try to take it apart and use the insides since they are supposedly the same thing. I would imagine this Riviera alt is a CS130D just different body? Either way its kind of dumb of GM to make a different bodied alternator for the same motor. Pictures of a 97 GTP shows an alt that looks just like the one in my 01 GTP. Even the Buick Park Ave Ultra looks like the same alt as the GTP. Im pretty sure that one is 125 amp. Unless because the Riviera was the first car to use the L67 in 1996 maybe it was before they decided to use the Cs130d and the one I ordered is actually just the CS130 and they kept it because the Riviera motor was already setup for that mounting style.
