Here's a helpful thread that gets at the 621 saddle RPO: http://67-72chevytrucks.com/vboard/s...d.php?t=654175

To my chagrin, I'm mistaken and this does appear as the dark saddle for 72. However, the same color uses RPO 688 in a 72 K5 and this led to my confusion. It would appear that RPO 621 for a pickup and RPO 688 for K5 are synonymous and denote the same dark saddle. If anyone knows otherwise please chime in.

EDIT:
Scrounged up this image posted by another member that lists the RPOs of interior colors. Note saddle only available w Cheyenne/Super level trim packages and those for buckets differ from that for a bench (same RPOs for parchment though, oddly). The saddle for a 72 K5 is only available with CST level trim.
