Passenger door latch ’66 Satellite

Hello,
Been looking all winter for a passenger side door latch, preferablly the whole setup, for a 1966 Plymouth Satellite.

The door will not latch shut unless the door button on outside handle is disconnected AND you push door on door!

Have messed around adjusting striker alignment, which is when I found out the combination to get latch to work!

Anyone have one or know where to maybe find one?

Thank you
