Appreciate the input! Not a big issue - just curious more than anything else.
My seats have the original covers and are both in great shape so no reason for anyone to swap sides. The drivers seat cushion foam is more collapsed than the passenger side, so I assume the seats have not been switched side to side.
With the knobs outboard, they are a bit tight into the rocker/carpet so this position did not seem logical. Yet, I have seen some pics of cars with them inboard and outboard.
I need to replace the rollers in both seats so I will fix it then. I will swap the seats side to side to take advantage of the better foam from the passenger side.
