Seat Issues:
1) Always moved around a little and rattled.
2) Sat to high for my taste.
3) Needed leg room after shortening steering column 3".
Fix, Lower seat: Got rid of all of the seat adjustment parts (never needed in my case) when doing the lowering. Making the solid mounts made a huge difference, fixed all of the above issues and now I feel like I'm in the truck... not on it.
Lowered the stock bench seat 1 3/4" using nothing but the stock sliders. Tried a bunch of different heights and this was the best option for me. This combined with the steering column shortening have made the cab MUCH roomier!
