68 GTS Resto

Are you referring to the vin# stamped where the trans mates with the block? Both the trans and the block have the same vin which matches the car's vin.

Asfar as the scheduled production date where would I find that. On the build sheet?

No, the pad under the distributor hole. Should have D383 plus other numbers. Which is the assembly date of the motor and maybe HP, maybe not?

The SPD of the car is on the build sheet. I'm not real familiar with '68 fender tags so don't know if SPD is on the tag?
