Anyone make any Sebring seat brackets...

Update:
After trimming as much material off the bottom of the runners as i could, i found that the seats still didn't sit as low as i wanted. after some thought i decided to cut the risers out of my floor, the raised areas next to the rockers, to effectively make my floor flat but angled up towards the front. Doing this should make it alot easier to make mounts for the seats.
I cut out the risers and the support pieces underneath, then welded in 1/8 x 3 flat stock pieces to the underside of the floor and tied them in to the outside (rocker) end. then i welded in .22 gauge patch pieces to fill the holes, the went over that with more of the 1/8 x 3 flat stock with the rears spanning the whole width of the seat area. I'm sure that the floor will now be plenty strong to keep the seats from tearing off the floor in case of an accident.
I'll take some pics when I clean up my welds.
