The 4 in the trim code denotes the color. In '65 and '66 4 was Fawn. In '67 4 was Gold or Champagne. In '68 it was Willow Gold (which was a greenish Gold).
So it looks to me like you've got Fawn.
I'll have to try and remember to scan the pages from the upholstery album.
This 98 has a Fawn interior:

Look at the carpeting, dash pad, dash paint and steering wheel. This is what you should have.
