Well I took out the back seat of my Road Runner today to run some speaker wires and found the build sheet under the bench.I wasn't expecting it because I knew when I got the car (about 2 months ago)that the seats where redone white instead of burnt orange,but didn't know when it was done.

The only thing is it's not mine.It's close but mine is a hardtop and this is for a coupe.My vin matches the title,door,and rad support so that's all good.
Was this common to find different broadcast sheets in cars?
