The actual interior codes are different from the GG1 interior callout, which is a general description of the color scheme.

In the old PPG #s, the interior greens are:
Velvet Green 43137 (lower gloss)
Catawba Green 43695 (gloss)
Catawba Green 43721 (suede)

Old DuPont #s:
Velvet 9075LH (low gloss)
Catawba 4883L (gloss)
Catawba 9507LH (suede)

Velvet Green should be the color you need; the gloss level when they were new was slightly glossier than satin, but not like exterior paint gloss.
Suede is the textured dash/column rougher finish.
