Re: 58 regulator

It will fit and work, mon! The primary difference(s) between '9000, '9001 and '9002 deal with how the internal solenoid air gaps and spring tension adjustments are set (cut-through, current regulation, voltage regulation) to option the regulator for its mating 25, 30, or 35A generator.

Any competent auto electric shop with good old days working knowledge of generator systems, can remove the cover from the regulator and 'tweak' its internal adjustments to be DEAD NUTS on for your generator/your car. But, absent the fine tune/final centering adjustments, any 9000 series V-reg should install and work...

Thanks for note. Will it be judged as being correct?

Of course not!

Re: 58 regulator

Do any of these 001,2, or 3 regulators indicate the change from top cover mount screws to side mount? My 57 has top screws but I read somewhere that the change over to side screws occurred in mid 56. It wouldn't surprise me if my regulator is not orginal to the car. -Dan-

Don, the 1958 Corvette use the 1119001C regulator.(all h.p.) That is what you will need for judging.They are dated by year and month,so take that into account when looking for one.

Re: 58 regulator

Dan all of the 111900_ (000,001,002,003) had screws that mounted from the sides of the cover,not thru the top of the cover.That change did happen early in the 1956 model year.

John speaketh with straight tongue!

The 8xxx series V-regs were the last to mount the cover with screws through the top corners of the cover. The 9xxx series regulators 'improved' the cover to the base mounting via locating the attaching screws in the outside lower flange area of the cover.

That shortened (cost reduced) the mounting screws, eliminated the need for washers/gaskets around the head of the screws and moved the holes in the base OUTSIDE cover/base moisture gasket.

The first variations of 9xxx regulators were embossed with their PN in a single stamp sequence (111900x) and lacked design revision level identifiers (A, B, C, D, Etc.). In 1958, the 1119001C came on stream and to get the identifying emboss to 'fit' on the regulator's mounting ear, the sequence was broken into two stamp lines: "1119" with "001 C" on the line below.

Note, the consistency of font and its specific placement on the regulator's mounting ears varies considerably from unit to unit. I've seen quite a few of the early 9001 regulators (single stamp line) where the date code was stamped SO CLOSE to the center notch that when the shock/vibration mount insulator was installed, the date code was almost impossible to read/verify...
