Pics of my 07A original water pump pulley, I notice the font of the part # of the two originals match and have a flat top #3. The numbers of the repop are not the same. Could that have changed during the model year?

My understanding is that the production date shown on the NCRS letter is the date GM officially considered the vehicle as completed, and invoiced the ordering dealer. It's often several days (at least) before the date the vehicle was actually collected for shipment, but the logistics of transporting so many vehicles away from the assembly plants explains the delay. Not sure there is a clear definition of when the car is considered 'complete' (especially if it triggered an invoice to the dealer, there may have been a 'substantially complete' build stage) but would think it reasonable to expect it was when the vehicle left the production line and passed quality control.

The production date listed on the NCRS reports - anyone know what that date is based on, and is it an actual date or approximate like the LOS Fisher Body scheduling code?

Here's the pulley off my Z - sorry, not the best quality image.   Hope this helps.

I tried to post a pic but the file was too large. I believe it to be a retaining clip for the spindle nut that holds in the bearing through the firewall.

More than that. That's when it was initially scheduled - it could have been built a day or two off.

Anyone want to post pics of an original for comparison?
