Help identifying a Delco alternator

[Falcon_LS]

The RPO code is KW2, which appears to be a 124 amp unit. I'm trying to find out the model number to order a rebuild kit for it. Thanks!

Call a rebuild shop.

Sometimes you can read the markings on the case. Its there, you just can't always see or read it. Another way is to look up the belt number if it is still there and read the description. Many times it will list the alternator amperage. You may have to cross the OE number to an aftermarket to get the alternator description.

If they existed around here, I wouldn't be asking.

Thanks, I'll give that a try.

Appears to be a ACDelco part number, 321-2149.

Got it, it's a CS144 series.

FWIW I have bought parts from alternators.com before, they worked OK. It was only once so this isn't exactly an endorsement, but I haven't had any problems since then.

I buy my alternator parts off of eBay.
