I've been looking for factory buckets since I bought the truck, but they seem to be extremely difficult to find. So I robbed my jeep of its Mastercrafts. They are damn comfy since they are suspension seats. I'll pick up some seat covers or something to deal with the olive drab color. haha.
Here is how the floor mounts look. I robbed these from a truck I scrapped out. I have to move the inside mounts over a bit, but the outside points were pretty much dead on.
