I have similiar seats in mine. Can't get any pics right now since my camera isn't here but basically you need to use 1" square tubing and make 4 brackets for each side that bolt to the original bucket seat mount locations then take 2 more 1" square tubing pieces and run across on the front and rear. The sebring seats probably have the front attaching points at about a 30 degree angle, those need to be bent down to 90 degrees and bolted to the front cross piece. The rear should be relatively straight out and will need to be bent also to bolt to the rear cross piece. This puts the seat up high enough so you can see over the dash. If you are tall and need the seat WAAY back you will have to modify the design. PM me your email address and I'll see if I can borrow a camera for a while and get some pics for you.
