1966 Build Date Help
I have a 1966 convertible and I’m trying to figure out the build date so I can make sure I have the correct A6 compressor with backing plate and also correct 3376 Holley carb. The Vin # is 194676S114625. Can someone help me please

That site is just a registry of cars. The one I think you want is the NCRS.org. You'll have to join the NCRS (the National Corvette Restorers Society), and then you can order the shipping report, which will tell you when it was built, and who the delivering dealer was.

EDIT: Just a reminder, that there is no database where all the data on your car can be found. You will have to search for it thru previous owners, previous documentation, or what you can learn by inspecting your car in detail. But we can help. NCRS will provide a build date and who the dealer was that the car was delivered to. That is it.

Your carb should be a #3367, and typically will have a date about 3-8 weeks before your car was built. They are a bit hard to find, and are not cheap.
The AC compressor backplate date will likely be 4-12 weeks before your car was built.........since not many 1966 Corvettes had AC, so they built the compressors in batches and then used them up before the next batch was started. My own 1967 327/350 HP factory AC car has a compressor back plate dated early December 1966, the compressor built in late January 1967, and the car built in late March 1967. The correct backplate may take a year or more to find, but can be done.

I just sent in for the Shipping Report for a 66 Roadster I just bought and the receipt from the NCRS said the results would be mailed within '30' days but I recall the other 4 reports I had
requested showing up a bit sooner than that. They will 'expedite' the Shipping Report but I'm in no big rush and wasn't inclined to pay the higher charge of $80 for it.

However for people that are trying to track their cars back to original owners and such it can be an important part of the puzzle. I have it for my 65 but already knew the selling dealer and original owners name and profession (Dr.) through the third owner but the original owner has passed away. This is becoming a common thing with cars that are approaching 60 years old. When you figure a Dr. freash out of medical school would be at least 25 years old with school cost to pay, establishing a practice etc.the could easily be approaching or over 100 years old.

Powershift,
I have the comp here in the shop. Just got back to work after a bout with covid. His info on owners was good, nd he has a Jan back plate. It is a true vette comp with the dish pistons and looks like it was never apart. As you know there was a hub clutch cosmetic change and a case cosmetic change to a swaged case. Those (the clutch & case were only used a few years, 64 to mid 66. The first 63's use that clutch and case, but did not have a foil. They had 2 spot welded tags on them. This is not to say that some 63's didn't have a foil, but I've seen about 20 original 63's. Also the 63 back plate only had 3 (3/8) mounting bolts instead of the 4 we see on all the rest. You are correct about the average time from back plate, comp assembly and build date. I think this is one of those situations where things were a bit closer, and batches ran at random. I also get date info from the front cover which also has a date code as on the back plate and they are usually within a Month either way.
I will know more when I get to his as the covid caused a back up in the shop.
Your friend Dom

Mark,
I am not familiar with the vin & trim tags, but am curious as to the I 13. The I which is rarely used, is used on compressors. It is Sept. Can you educate me as to it being April on the trim tag?
Thanks, Dom

On the Trim tag A represents the first month of vehicle model year production. That can vary between August and September. Most start in September. I have never committed to memory which years started in July and which started in September. So I often have to check. You can see this differs significantly from component dating which starts at the beginning of the calendar year rather than the beginning of production for a model year. That's why the letter I does not represent September in all cases.
