Default 1969 Corvette Alternator Description

I have a 1969 Corvette 350 with A/C. I am looking for the correct part number Alternator, but Not date correct. I have seen several that appear very different from each other, peticularly the fan. Some have a one piece fan/pulley, with a larger housing, and others have a two piece fan/pulley with a smaller housing. Do you have any photos? Paul Spencer (561) 965-0777 or eves (561) 968-1781

Hi Paul,
I believe the pulley for your 350 with A/C depends on whether the car has power steering or not.
No PS...2 3/4", no part number, stamped 2 piece construction, black phosphate plated.
With PS...machined 1 piece, #3909817 AW , zinc plated.
Regards,
Alan

Thanks to 68-69 Tech Manual.

This is from "Corvette by the numbers" , Alan Colvin:

1100825 is a 61 amp with A/C, and is used interchangeably with second production alternators 1100882 and 1100884.
