Tail lights not the same on both sides

I replaced the sockets for the tail lights. Driver's side lights all shine. When the brake is on, both lights shine.
When the turn signal is on, both lights shine and blink.

Passenger's side, brake lights on, both lights shine. Turn signals, only one light blinks.

Reverse lights work just fine.

Which side is lighting correctly? Did I wire it wrong?

Does anyone know where to get rear tail light assemblies for 1996 Pontiac Trans Am?
I need both sides, they are being held together with glue and tape.

Thanks
