For those using Sebring convert seats-how did you brace the floor pans.

I have a set of Sebring convertible seats but looking for ideas on how to beef up the floor pans for extra support since these seats have the integrated seat belts. Ultimately trying to hash out whether I go with the Sebring seats (already have modified seat tracks and holes drilled in floor pans but will need more supports) or have the 73 charger seats I just picked up get new foam, new hard back covers,recovered and run the old style lap and shoulder belts.

mine were pretty flat since I used a 73 rear floor pan and had to bridge the hump cutout using flat stock (18gauge 12"'16" )to let the seats mount in the stock position

I did mine the normal way for older cars. I used a 4" x6" rectangle of 1/8 " plate and welded it to the floor pan. it also was welded to the rocker panel drop in a couple palces on the out board sides, the inboard side was done by bending the 4" wide strip of 1/8 the same shape as the tunnel and welded in to the tunnel drivers inboard front side to passengers side inboard front. same for the rear mounts . it isn't moving anywhere. I could have gotten away with just the (8) 4" by 6" plates bent to fit the floor pan since the belts are anchored to the seat frame instead of the floor like hardtops. since the outboard sides do weld directly to the rocker panel drops and the seatbelts locate on that side too! rears were mounted using the sebring cross bar from the convertible and welded solid to the riser bar from the old convertible boot well. I cheated and used 1/2 angle iron to back weld nuts to so I coulld thread in bolts like thew original sebring setup THEN drilled holes to go through the angle iron and floor pan+ 1/8" bracing.(4"x 6")
