Not sure where to start - 69 Z/28 on BAT

[RSSSfan]

Regarding the engine assembly stamp being 2 months before the trim tag date, I realize that it may be feasible that the engine got pulled off the line for some reason and was delayed being installed in the car - I'm not calling myself an expert, so perhaps that date range is not all that uncommon. But the fact that the trim tag has been off the car AND the block in it now is a restamp, it looks suspicious to me. Seller is going to have to provide a picture of a legitimate VIN stamp to prove the veracity of his claim.
