Ok here's a question on a billing history I got for a 1967 bird. There is a box for option 55 - power windows - and there appears to be a number 4 in the box although it is hard to make it out. The car does not currently have power windows but the interior is the correct original color. According to the list I have, a power windows car would have a 1 in box 55, not a 4. Trying to make heads or tails out of this one...why would it say it had power windows if it doesn't have them? So far, everything else on the sheet is correct. Thanks!
