Correct Alternator

[Roger D.]

Am I right to think my 1969 base model vet 4spd, no AC requires the 859 alternator to be correct for NCRS?

Re: Correct Alternator

You are correct, but it also needs to have the 7 cooling fin rear housing which can be very expensive.

Thank you Ed, Ken Bruno has one dated from Nov. 68. My car is a Nov. 68 build. Just a coincidence . $700. I have seen them as high as 900. He is sending me some pictures.

Re: Correct Alternator

Good find Roger! You could also give John Pirkle Jr. a call, I think you may have heard of him.

Re: Correct Alternator

Roger, yes, these things are one of the more expensive items to find for the 69 and 70 Corvettes. $700 is about average but I've seen them up in the $1000 range as well. BUT... If you keep an eye on Craigslist, you sometimes get lucky. I got my 1100884 for $200 plus shipping a few months ago so the deals are still out there. Yes, it needed to be rebuilt/restored and it's not the "correct" date for my car (it's actually an early 1970 dated alternator), but at $200 I couldn't pass it up. Besides, I don't have my car judged, so I really didn't care about the date. But if you do, make sure the alternator you get is dated BEFORE your car's build date.

Oh yes I have heard of John Pirkle. I took me from the 1st week of June till know to get my correct starter. John said he shipped it yesterday so we will see when I get it.

Ed I thought I had a 6 month window on original parts. My car is Co4 which I assume is Nov.4th. I think the alternator is like Nov. 8

Re: Correct Alternator

Generally, parts that are dated up to 6 months prior to the cars build date are acceptable by the NCRS. However, high volume parts like the base alternator are generally dated much closer to the build date of the car. Most are dated just a day or so, to a few weeks prior, but again, there are always exceptions. But your car is C04 which is October 4th, 1968, so a November 8th dated alternator would be too late for your car. You need a date earlier than the cars build date. There are no components that are installed from the factory after the car was assembled so everything needs to be dated before then.

How about an 859 dated from July of 68 would that be close enough for a 69 build date Oct 4 68 for judging???

Re: Correct Alternator

Yes it would. There was a strike that started on April 10th, 1969 that lasted 8 weeks (with another two weeks to gear up completely) that screwed things up date wise for late cars, so you'll see components for these cars ranging from early in the year to late in the year. For instance, my car was assembled on October 21st, 1969 and the M20 transmission is dated P9H16A (June 16th, 1969).

Thanks Ed he may also have one from early Sept. I would assume that would be a better one.

Re: Correct Alternator

Either will work date wise.
