1963 Delco voltage regulator timeline transition from 1119512 to 111951

[Michael G.]

Regarding the 1963 Corvette, what is considered the accepted timeline for transitioning from the 1119512 Delco regulator to the 1119515?

AIM shows no change during the model year.

Michael, please read the quotes below, from an earlier thread on this subject:

Can you help on more specifics as to when the change occurred in 63 Corvette production from the 1119512 Delco-Remy voltage regulator to the 1119515 D-R voltage regulator? Thanks, Pete

The entire electrical system was newly designed for 64 which included the new 515 regulator.


GM still stocked and sold the 512 regulator for a short time after the new 64 model cars were released.


As Alan mentioned, the AIM shows no part number change. My original GM copy of the 63 AIM, which included much more information and later entries/revisions than currently available reproduction/reprint copies doesn't show a part number change either."

Bill - I guess those Production guys didn't read the judging guide. Pete

That happened often.

Typically if such a change ocurred it would have been due to a parts shortage during build-out where the Engineering Liaison to the plant had the ability to verify the application suitability and pull-ahead the coming model year part. Typically this would be limited to the last few cars off the line (hours or a couple of days at most)
