My alternator is not the original and I am trying determine what is the correct unit.
By the Numbers says 1100833 for base 427 but also says 1100881 "2nd Production".
I have found either part for sale with date code that corresponds to my car (date code 8K?? for Nov 68, my engine was assembled Jan 69). Anybody know what "2nd Production" means and better still which is the correct alternator for a 69 427-390 w/o A/C that was built Feb 69 and has engine assy dated Jan 69?
Thanks for your comments.

Not sure about 2nd production The specification info show coupe and convertible.
 
it shows that for 427, 390,400HP should have 110083
427 430,435HP with transistorized Ignition should have 1100882
 
I can Email you the specification pdf file it is 56KB in size if you would like it shows all the info and specs

I did find this info that might help
 

The 1969 Corvette build cycle was from September 1968 until December 1969.
One of the longest build cycles for a US car.

Serial Numbers: 194379S700001 through 194379S738762   --   For Convertibles, the fourth digit is a "6"

Fisher Body Style Number 69-19437 identifies a Corvette Stingray coupe
Fisher Body Style Number 69-19467 identifies a Corvette Stingray convertible
The body number plate is located on the engine side of the cowl

The early/late changeover was at approximately SN#18,744 in March 1969. A good rule of thumb is to check the vacuum actuator located on the right side of the firewall. The actuator was changed from the "can" shape on the early 69s to the "double pie plates" shape on the late 69s. This is not always accurate because some of the late 69s have the "can." Many of the parts changed during production, and early and late does not necessarily have anything to do with when the car was built. Even worse, some of the very early 69s used parts leftover from the 68 run, and some of the late 69s have parts that were supposed to be on the 70s.
