Looks a lot better
Where did you find nice 85-6 front seats?
I just steam cleaned my carpet and seats for my 85. It all cleaned up nice like your interior did, but my seats are really faded along with the trans tunnel on the top.
Since your car has the original repaint, a good hosing with a pressure washer would probably strip most of the white off. Tape to the door jam will remove some of the repaint and will uncover the unit #. Worked on my car.
I wish I could get my dads 82 out and cleaned up...
