I found one bolt in the center of the seat, underneath the front lip towards the floor... but that's only for the bottom portion. How do I get the fold down portion out (the seat back)? I'm assuming there's probably another bolt for the lower portion of the seat underneath the seat back after it comes out... but, instructions on how to take them out would be a big help. Thanks.

 

If it's a 1 piece rear seat there's a small bolt under the seat--right near where the retracting seat belt is(pre-89). If you stick your finger there you'll feel the bolt--just loosen it up, I think it's a 7mm but I'm not too sure. There's 1 bolt on each side so you'll have a total of 2 bolts. for the 2 piece rear seat it's the same thing except once you take out each bolt you have to slide the seat back out of the rod that's in the center(welded to the hump).
Hope I made it clear--it really is very easy to do.

 

I just took mine out out recently and it's real easy once you figure out where the two bolts are then you just got to slide it off the center bar, like Tony said.

 

and the bottoms are only velcro's at the back

 

There are 2 either 11 or 13 mm bolts, I don't remember, holding the fold down seat back in. One on each side just below the hinge. You'll probably need a wrench, I had a hard time fitting a rachet in there. They are easier to feel than see. Just take the nut off each hinge and it comes right out. Took me about 2 minutes to do while swapping seats. I put a step by step on this in t he thread I posted a while back called "Check out what I did this morning" or something like that.

 

I believe the nuts from the folding seat back are 10mm, and the center bolt in the middle of each seat bottom is a 13mm.
