Removal of back of front seat ash tray trim, P-20

[50PlymP-20]

I’ve done several searches on this topic but haven’t hit the jackpot yet. I’m trying to remove the 2 chrome trim pieces on the right and left sides of the ash tray on the back of the front seat. I don’t see any fasteners on the other side of the seat. I tried tapping/sliding them toward the side of the seat (door side)…but no movement. It’s an P-20, Special Deluxe. Any hints?

It's been probably 20y since I messed with those on dad's 50 but I believe they were held in place by pins on the item and those little one way clips

Thanks, YoungEd…I’ll take a closer look.

When I went to an upholstery shop today for a quote on redoing my seats, the guy just pushed the trim pieces out from behind. Here’s a pic of the backside of the trim piece. Mystery solved.
