Just a WAG, but the top one was likely a seat assist spring. The service manual mentions "seat assist springs" but doesn't really show them in a picture. They were one of the few missing pieces on my truck. I think they go from the front of the seat riser (small hole near where the adjuster bolts on at the front?) to the back of the seat frame (the moving part) to help move the seat forward (uphill).
Your second one looks familiar, but no real clue where it might go. Maybe on the latch lever on the seat adjuster to keep it engaged?
