'68 Valiant Rear Seat Removal

Hello. I looked through many threads on "rear seat removal" and only found old threads that are inactive. Also, I didn't see any reviewing how to remove the rear seats from the '67-'69 Valiants. I don't know which other years Mother Mopar installed them the same way and on which models, but I need help figuring out how to remove them. My brother and I both climbed into the back of my poor car trying to figure it out, to no avail. Would there be a picture of this in a shop manual or one of those repair books you can find at an auto parts store. I'm trying to find (I hope there is one) a build sheet.
