If there is no difference in the bucket seats, when putting them in one of my vehicles, I would put the most comfortable one behind the steering wheel. See if the other one is more comfy. If you turn the seat upside down many times the material is "hog ringed" to the frame, pair of needle nosed pliers and twist the ring open, lay back the vinyl, install new cushion, relay vinyl and hog ring back together.
God and family, the rest is icing on the cake.
I'm so far behind, I think I'm in first place.
