How many 79 Trans Ams were made with black interiors

I have a 1979 Solar Gold Trans Am, sporting an all black interior. I have been trying to do research to find out how many may have been made with this option. I know it was a customer order (build sheet found on top of the fuel tank) with the performance option, suspension option, 4-wheel disc brakes, T-tops, rally gauges, etc. what I am trying to figure out is how many gold with black interiors were made.
Also, I am also trying to figure out this "Gold Special Edition" legend/myth. The car is in pretty good shape considering how long it had been sitting when I found it, however I can see that body work has been done to it. What I noticed is the pin stripe decals, (painted over when repairs where made, awful) around the rear window of the body panel. Did the gold TAs from 79 have the special edition decals? Was it an option? I am ordering PHS documentation tomorrow, I am just being impatient.

Any insights would be great.
