      04 GTO Seats in 68 GM A body... How?

      Hi im looking for a writeup
      For a proper Gto seat installation in a a-body.
      Of course i saw a couple chevelle treads already but everybody has a different approach.

      No show quality needed!
      Proper driver installation is fine.

      The rears need to be trimmed i heard, the front seats need brackets or can i reuse the oem gto brackets?

      Help a dummie.. Lol

      First yes the rears must be trimmed done ..peel of the leather and foam and go to town , separate the seats from the Styrofoam center section as well being as the width isn't correct either . For the fronts you either make your own brackets or yes you can modify and use the power seat base . The biggest complaints being the height so you need to modify to make everything as low as possible. My idea is to look at lowering the floor where the seat bolts to ...an inch isn't much on the floor pan but will be on the seating position.

      No not really ...youre going to have to do some digging I have seen pics where guys have cut the power seat bases ...maybe copy their ideas . Want to think "project overtime" and yes there might be a few but the one is a nova ....I think he was the guy who cut the bases where I got the idea from search project overtime nova maybe

      Use the OEM tracks if you want to keep the power seats. You will need to make a small bracket for each corner, mine are out of 1/8"x 1 1/4" flat stock, bent in a vise. LOTS of work but worth every minute. PM me your email for a few pics.

      The rears, once cut apart as described above, fit better than you might think. It's fastening down the front of the base that's the hard part.

      If possible find a gto donor and get the piece of the sheet metal the rear bases attach to . Then graft that to your floor ..I have the pice just haven't grafted it to the floor

      So do you take out material off the rear seat bottom section?
      How much off the rear top section? Do you cut the frame part and weld it back together? Or leave it "open"

      I remember using many of his ideas, except that. Good idea if it's available.

      My car is a bench seat model so i have two holes on the driver side and two on passenger.
      So i have to drill new holes regardless and i dont mind.

      Do you have a positioning template or did you just test fitted it.

      As far as i understand there are two options to make the front seat rails fit. (rear 45* bracket)
      1. Cut the 45 off and attach. Brackets as in pic
      2. Build a 45 angel bracket and attach this to oem bracket.

      Are you guys just shimming the floor part to make sure the seat is leveled?

      I think most people are using their stock belts. the rears would mount kind of funky and they are 3pt.

      Stock seat belts here. Front brackets are easy. The rear brackets take more fabrication. I have a 1965 Buick Skylark.

      Stock seat belts here but putting the GTO ones in at some point. I just used large circular welding ground magnets to hold the seat bottoms down, they aren't going anywhere. For the uppers, I put a rod across the hooks in the upper seat back where the original seats mounted, then just hung the gto uppers on it. My rear needs to tilt a bit to get the top up/down though so that might not work for a hard top.

      This is the only one I have and it is in the mock up stage. Flat stock was used for the front and welded to the seat rail. The rears were two piece with the top piece welded to the GTO seat rail and the bottom piece bolted to the floor with a slot for back and forth adjustment. Than a bolt through the back side to bolt the two pieces together. The object was to get the seat as low as possible so my head would not hit the headliner. That part worked out just fine as I have enough head room. I am 6' 1".
