Build Date Of A 64.5 - Missing Door Tag

[Agust Torfi]

Hi

I'm new to the forum - and a new classic mustang owner - have a number of classic cars but this is my first mustang.

So, the door tag is missing - and the seller, second owner since the seventies, tells me the color and interior are correct as well as original engine and that seams to be true.

But I really want to get close to the production date. Any help here?

VIN# : 5F08D144860

Thanks
