Ok, in the pic below with the yellow circle, it shows the plastic cover location on your seat. Remove that, it simply pops/slides forward to remove them. In the second pic you will see the bolt I am talking about, remove both on each seat but only the front. You might need to loosen the back two on each to get the seat to tilt back, but do not remove them all the way.
Once the bolts are out and the back bolts are lose, you will be able to push on the back of the seat and create a space between the seat frame "arm" and the body of the truck where it was mounted. I put the washers on the between the body where the bolt screws in and the under side of the seat "arm" then sat the seat back down on top of them. It causes the seat to have a new natural rise and doesn't impede on any movement of the automatic seat. I added and removed washers to the height I wanted, with the auto seat all the way in the down position, front and rear. Pic with the arrow....do the front of the button and the back of the same button. The seat will adjust as it always did, but the new lowest point it will go will be higher than it was before. That way, when I adjust the front of the seat to rise with the auto adjuster I don't have to go to it's highest point to be comfortable, which caused my legs to fall asleep after long periods of time. Once you find your right height, put your front bolts back in.....tighten to snug, then tighten down the rear. Hope this makes sense, sorry for borrowing this thread...cheers!
