Hello.If you 'll look at the vin on your car I think that you'll see that the second digit is a T not a 7.The first digit is the year model.The second digit is the plant that built the car and they only built Mustangs at three plants.Dearborn(F),San Jose,cal.(R) and Metuchan N.J.(T).01 means that it's a coupe and C is a 289 2bbl.The rest is the sequential number of the car.There's a number after that 9 also.It should be 6 digits.That's all that the vin can tell you.There should be a metal tag held onto the latch area of the D/S door by two rivits .It will tell you what the original color was rumoured to be

.You can buy a new one for about 20 bucks and it will say what you tell it to say,so there's always some questions surrounding the door tag data.Changing the interior color is not something that you'll be able to do on a saturday afternoon if you want it look right.You can re-dye the carpet and have it look pretty nice.You can't really do that to the seats,dash pad,door panels,arm rests and rear trim panels. You might want to just save up and replace those items.It will look much better and be far more durable.Hope that helps.
