Alternator Help

[fstblk66]

I have a late 66 coupe 427/425 (L-72), the alternator is the 1100693 37 amp. According to the 1963-1967 Stingray Fact Book all 66 L-72 came from the factory with the 1100696 alternator. I have heard from several sources that the late 66 L-72 also left the factory with the 1100693, can someone please shed some light on this issue for me.

All L-72's required K-66 Transistor Ignition, thus they all had the 696 (42-amp) alternator; the only '66 427 that used the 693 (37-amp) alternator was the 390hp L-36 without Transistor Ignition or A/C. A previous owner must have replaced the original 696 with a 693; the 693 was the "base" alternator in '65-'68 for almost ALL Chevrolet products, and they were very plentiful.

The 696's are EXTREMELY difficult to find - the specialists (like John Pirkle) have a LONG waiting list for customers looking for 696's, as their only application was '65-'68 Corvettes with Transistor Ignition.

Sounds like that's the next Corvette Item to become a Forgery......

"Hey, how can we get "Broch" marks on this Alternator case....."

Well looks like the search will begin, thanks for the info.

There are already LOTS of restamp 696 alternators out there - most of them not very well done.

Soon were going to have to hire experts like yourself to inspect parts before we buy just like we do when checking out a complete car..
