Registration is on-going and many have asked where they can locate the serial numbers.
To help, we have these two images that will help you narrow down where you are looking.
We realize that your motor is in the car, but hopefully it is clean and easy to get the numbers since most have been in the shop working on cars at the time of this posting.
