Thanks Goathead for steering me to this thread. Somewhere, I have a magazine article clip from an old issue of High Performance Pontiac that gave the production number for Custom S converts. Gotta find that again.
Here's a pic of my Custom S:
About 10 years ago, I wanted to replace the black interior but ran into a dead end finding the correct seatcover material for the factory bench seat. So I discarded it [!] (shouldn't have done that) and replaced it with a pair of '69 GTO buckets. With no specific Custom S style seat pattern upholstery available, I was left with no other choice than to replace the whole interior with correct pattern [for LeMans/GTO] upholstery. I assumed at that time that a Custom S could have been ordered this way [with buckets]. I am finding out now that apparently, they were never offered with buckets. If anyone knows otherwise there's a $10,000 reward for that documentation.
