Those are in very decent condition. Look to be from early 70's by the switches. Most of the parts were universal for all Mopars that used power bucket seats. It is a time consuming job to take it apart and clean/lube everything. But worth it. 60's models had a single switch that you could push fwd/back/up/down and twist it to tilt the seat. So the switch mounting & seat trim is year/model specific. I believe they will bolt right in to any c-body. One note, seats from a 4dr will not fold over to allow access to the rear in a 2dr.
Take photos of how it's assembled before taking it apart.
