Seats with integrated seat belts

I have a pair sitting in my Daughters Car trying to figure bout the "Tracks" and how to mod them so I can bolt them in. ('65 Barracuda) I will beef up the floor. Pics. speak louder than words for me. LOL! thanks, Tim:happy1:
mine are ugly but you will get the idea of how easy the sebring bolted in
I just used 1"x1"x1/8th angle and drilled for the stock sebring seat bolts. then I did another bolt (3/8th by 1 1/2 grade 8) that went through the floorpan with a 3"x6" 1/8 support plate on the bottom. if it tears out now there won't be a car left to fix! them babies are in solid pic 3 shows the circles where I was drilling the through bolts.

both rear inner seat brackets close to the hump were turned so that the angle was down insread of updo I could drill through and weld a nut on the bottom

the rear seat pan was made 44"x6" with a 1" lip like a j channel used in vinyl siding (to give strength and something I could weld the mounting brackets on to.

black circles are where I drilled throught the bracket and floor pan using the support plates on the bottom of the car. the 2 inner ones are close and I should have made them 3 inches long instead of 2 but they fit!
