how do you do it? '68 camaro

Welcome to the Club! Grab the seat bottom at the floor with both hands with each hand at the middle of the floorpan. Push back about an inch or two, lift up. Seat bottom will unroll out from upper seat back.

After bottom is out, you will notice two bolts holding in the bottom of seat back. Remove the two bolts, grab the seat back and lift up and pull out.

Count all the change you collect, and other stuff left underneath the seat.

I took mine out last night. Now my front seats are out also so it made this very simple. I laid down in the floor board and put my feet to the front against the lower part of the fire wall. I then reached in under the rear seat to feel the latch where the rear seat hooks in. I then put my shoulder against the rear seat and pushed enough to push the brackets back and up. Did one side at a time and had no problems.

Oh and BTW, I only found 55 cents, an ink pen cap, a crayon, and a bunch of gum wrappers.
