New to the forum so if this posts all jacked up you will understand....not sure if the pic is posting
Car: 73 Mach...Ii do not know the exact build date, but its a late June car. The engine build date per the valve cover date code label is June 18th.
Interior is white (code GW?) and the centers as shown are solid vinyl, not comfort weave. Perhaps this thread explains why I cannot find *exact* replacement repro interior. ??
BTW...i have owned the car since '87, and yes I am sure thats the original seat cover
Welcome to the forum and to the ever growing number of all vinyl Mach 1 interior owners! Your seat material and your suspected late June build date line up perfectly with the fact that you have the all vinyl interior. It would be great if you could provide a Marti report for your car to confirm your actual build date. Also, I would like to see a photo of your rear seats if you could post that. I ran into the same issue you did when thinking about replacing my front seat upholstery. I couldn't figure out why my seats were so different from other 73 Mach 1's and why vendors were telling me that my seats had been replaced at some point (but I knew that they were original!). I have decided to keep my all vinyl interior as it represents a unique feature of the last few weeks of production of the first generation Mustangs. I will add your name to the list.
