Someone else will have to advise as to the significance of the 7E. As to the regulator, if it is bad, you will have to replace it with a good unit. The single/dual element regulator used with alternators from 1963 forward can be purchased today in a solid state version that will accept an original Delco cover. Previous regulators, ones used with generators are the three element variety (voltage regulator, current regulator and cutout) and for which no solid state replacements are currently available, but facsimiles of the original are still made in the USA of all places. But they are not great and an NOS while expensive, will likely last your tenure with the car, unless you are lucky enough to be 21. These are not rebuildable in the sense that they are made to function as new. They were not manufactured to be repairable beyond attempting to clean up the contacts, re-adjust and re-finish the cosmetics. It might be asking too much for a genuine NOS 7E! But who knows....

The 1119000 regulator is for a 25 Amp generator, common on passenger cars, but not used on Corvettes. AFAIK all Corvette generators were 30 Amp units and would have used 1119001 30Amp regulators.

I've known for some time that the later solid axle Vettes used the 1119002 regulator and I figured the matching generators were 35 Amp models. Thanks for the confirmation.

That information from John Pirkle references the part number, not the date. The regulator used on 1962 Corvettes was 1119002E. That is per John’s info. (It would then have had a date code like 62A (January) or 62E (May) 1962. In the case of the OP, the 7E is a date code—May of 1957.

I think we're talking about two different locations of the E. Yours is after the part number, the other is in the date code. See 62corvette's post above.
