Same as above about your engine verification.
Have to have the P-o-P
That is the only pure defacto way to authenticate.

If you do not have it , the only thing you can do is compare the date code of the block against build date of the car.

Distributor Cap is not assembly line correct for your car.

Since I don't see a date code on your front drum I suspect it is an aftermarket replacement.

And we still need to see the stampings around the valve stem of your spare wheel.
