The 834 and 837 alternators used the same fan, P/N 1966990.

Ed, I see many 837 alternators with the "hook blade" , but my 837 had never been apart until I rebuilt it. It has the same fan as my 834(like you said). I always wondered if it was correct as it was not the hook type, but assumed it was because it was all original on my car when I bought it. Another post reply by JohnZ concerning 837 pulley finish started by DT shows the hook fan. Could you clarify why this is? My engine is a 396,not a Z.

Can you post a picture of the fan you're referring to? Also, have you read THIS and THIS?

I wouldn't think any did - the alternator part number defined several characteristics, and if any of them changed, the alternator assembly part number changed:

Current output and curve

Physical "clocking" of front and rear case castings

Type of fan

Type of pulley

None of those attributes changed during the 1969 model year run, and neither did the alternator part number.

How about the 814 from '68 ? I've been chasing one for years - prices keep getting somewhere just above stratospheric and below sub orbital - I've nearly thrown in the towel.

After 40+ years of use and rebuilding, swapping, etc...  any combination is possible in a used part.  I wouldn't put much stock in what I found in an ebay part or C/L part.
Re the 814..  didn't I just see one on ebay yesterday?

I too had/have been looking quite a while.  I found one that needed rebuilding fairly reasonably priced, but it was the wrong date for my car.  So if anyone finds a date that's good for my car, I'd be willing to swap mine if that date works.
