1969 Voltage Regulator Date
« on: July 14, 2019, 12:32:49 PM »
What would be the correct dated 515 voltage regulator for my 04C 1969 Z28? Is 4D too early?

There were almost 4.5 MILLION GM cars and trucks built in 1969 and 99 percent of those used the 1119515 regulator. Literally thousands had to be built every day so, with the exception of cars built very early in the month, most will be dated the same month as the build date of the car.  In your case, a 1969 Camaro assembled the 3rd week of April, 1969 would also have a April, 1969 regulator, so go with a 9D.

Thank You very much for the clarification. I meant the date 9D on the one I have. I thought it was possibly too late for a 94C built car.

I was just going by what I observed on my car. It has it's born with reg dated 8L (dec of 68) on my 02B car built on feb 13th. I figured a month prior is good.

Most are the same month or the month prior.

Would the starter motor dates also be same month? I have a starter motor that is the correct part number however it is two months earlier than car build date.

Depends on which starter.

Starters were installed on the engine dress line at Norwood (or LA), and if we're talking about a common starter, like the one used on the LF7 and Powerglide, then it would probably be dated very close to the car's build date. However, if we're talking about an uncommon starter, like the Z28, it could be up to a few months prior to the car's build date.

Going by your signature, you have a 6 cylinder 67 Camaro, and since the 6 cylinder engines only accounted for (approx) 26 percent of sales that year, a 2 month spread probably wouldn't be that abnormal.

According to the 1967 Chassis Service Manual (and Chassis Overhaul Manual), the 1107399 starter was used on all 1967 153 (4 cylinder) engines, 1967 194 (6 cylinder) engines with manual transmissions, 1967 230 (6 cylinder) engines with automatic transmissions and all 250 (6 cylinder) engines, so I'd say it was fairly common, but probably not common enough to have a huge stockpile on hand.

It's common. But I wouldn't sweat the date unless you stumble into a better one.
