The date code on the automatics is on the pan of most GM transmissions from the late 60s . You can swap the pan to another transmission (PowerGlide or TurboHydro) of the correct casting and have a correct transmission.
I believe the date code on the Muncie is what the OP is asking to clarify, not the VIN.

MC - Saw you've had a few posts already and scanned through them and if no one else said it already...Welcome to the Corvette Forum.
Also saw you mention you had what you believed was a potential overheating issue with your 67 L71. Did you get that rectified?

Your the first welcome Mike, thank you I am looking forward to reading the forums and posting my issues.
As far as my heating problem with the 67 L71, John Z gave me advise about the vacuum advance and I ordered a upper radiator seal kit for an A\C car from Paragon,I got that idea from the one on my L 79 car withA\C,but Its been cold and nasty weather here in Missouri so haven't had a chance to put the two to the test, I just got back from a couple months in Arizona. Maybe I'll look you up when I return next year.Thanks Vet 65

MC - Those two suggestions were going to be the first two I was going to recommend, repiping so you get full manifold vacuum to the distributor vacuum pod and using that upper A/C rubber flap to help direct additional air through the radiator instead of some of it going up and over. I'm guessing your visits to Arizona are to the Phoenix/Scottsdale Valley and we're about 90+ miles due north of that area but if you do find yourself up our way, do contact me and stop by for a visit. And if that return trip to AZ has you here around late September, the Prescott Vette Club has their annual Vette Show
at that time with about 300 Corvettes with about 30-40 midyears and solid axles Vettes in attendence.

Ya Mike that made good sense to me also, I'm anxious to see the results. I winter in Casa Grande and know where you are located.....not too far away.
DZAUTO thanks for your info, I just purchased this car....67 coupe,L79 with a\c and power steering,(I did the # checking) I have had many of the C2s and C3s over the years but never much checked #s ...just drove em! My last car before this one and the L71 was a 66 427 390 roadster non matching engine, it was an IL block out of a 68 which I built back in 89 but I had it for 32 years so the # game is somewhat new to me, which brings me to the carb date on the L79 of 1711, it has the correct 3810 list but don't know the date.
Thank you guys....MC

The digit for the year (in this case, 7) is NOT, repeat, NOT the year it was assembled. It is the year model of the car it was for. Thus, MOST PROBABLY, it was built Aug 24 in 1966 for a 67 car. Yes, that seems kind of strange, but that is how the date codes for Muncies was done.

My '67 was built Oct 24, 1966 vin 2483 well documented, so his car vin 07032 was built in Dec. 1966. That would make the Aug build of the trans reasonable.

I have an NCRS shipping document that came with the car stating the production date was Dec. 29 1966 so ya Bluestripe according to your info mine should have the correct trans. Thanks to all again......now back to work on the L71 heating problem!
