Difference in their rebuilt parts?
Good day guys
I started up the Corvette after a long winter nap. The alternator seems to be fried. I used to have a place just down the road that would rebuild them. He has gone out of business.
My question is, of the major suppliers like AID, Auto Zone, PEP Boys, NAPA, etc, is there really a difference in their rebuilt parts? In case it matters, the car is a 1969 (Delcotron)

You may want to have your alt rebuilt if it is original, they have part numbers and date codes that match your car, if it is the original alt. Most the rebuilders do a crap job offshore or Mexico. They throw brushes and a voltage reg (if you're lucky), and spend most of their budget on cosemetics and a fancy box. They even have rebuilt bearings! You get what you pay for. If you want a good one, get a Delco. I worked in the parts business for too long. The good news is that if it makes it the first month or two, it will probably last.

Just rebuild it yourself. All the info is in the Chevrolet Chassis Service Manual for your car. The parts are inexpensive and good ones can be bought at a "starter and alternator" repair shop or at NAPA. I wouldn't buy any "Dura-junk" parts at the 'Zone' if you paid me to do it.
If you don't want to repair it yourself [a very inexpensive and simple job, as long as you don't need to replace the front bearing], just let the "starter & alternator" repair shop do it.

Sometimes C3 owners put upgrades on their cars, I have known a few, and they require more power. Or sometimes someone is stock and might want to add a boom box and big amp in the back or electric fans in the future.
I know this might sound like complete fantasy but it does happen. 100 Amp alternator isn't going to hurt anything unless it's a stock vehicle and he wants to keep it looking stock for whatever his personal reason is. But he said he is looking at aftermarket rebuild anyway.
Upgrading to a 100A alternator wouldn't be that much more than getting it rebuilt. It is not as cheap as you think, they only work for $4 a month in China and few other places. Here no ones looking at it for less than $20 / hr.
You can also upgrade the SI alternators internally to 96 amps and there is no way or very difficult to detect. Does that answer the question or no.
BTW when are you moving to Ontario ?

I would buy a Delco rebuilt. They are available at a local Delco store or Advance or O'Rieleys. I would not turn in my core if it was original to the car. The other option would be a CS144 alternator conversion (stay away from CS130 IMHO). Like another above I would not use a Duralast alternator as a paperweight.
