need help/pic 66 Barracuda seats

I'm about to finish the interior in our 65 Barracuda and just getting to the front bucket seats - from a 66 Barracuda. For the life of me I cannot remember how the seat back stays attached to the seat bottom. It appears that it slips over the pins on either side of the seat bottom and it's just held in by the lower outer covers, can that be right? thank you.
