Tiny, you can check out the seat on my '56 3100--pics are in the gallery (Arch "56picup" Oetken's). It is the middle seat from a '99 Tahoe. It allows you to flip the seat up, pull the back forward (both for storage) and gives an arm rest/drink holder--and is below the back window. No power.
When considering whether you want a power seat, keep in mind that you probably want to position your seat as far back and raised up as far as possible for leg room. Also find a seat with a very thin back if possible. Using power for moving the seat forward/back would not be a real plus unless you or your significant other is a real shorty and are constantly switching drivers. Hope this helps.
