    Theoretically you could by using the stock seat mounting points, and extension straps - You'd have to rig somewhere to hold the anti-submarine belt in place.

    I used the seat mounts. The rear-seat mount behind the driver was used for the other point on mine. It's a temporary thing for when i need it for racing.

    I absolutely would refuse to have a 3 point harness like you describe. Where's the force going to be applied to your body in an accident? A 4 point harness would be far better in my opinion, applying the force to your pelvis.

    Tim make a good (and hilarious) point. The 3 point harnesses tie to the sides like a regular lap belt and if you could picture an upside-down Y on your chest with the bottom part of the Y being the attaching point at the back of the seat or rollcage. I will also get probably some 3 point harnesses. I won't do any racing, I just like the look of them. The only thing that sux is that they don't allow much movement to the occupants.

    all the 3pt harnesses i have seen are over the shoulder.
    it has two straps over the shoulder, then one inbetween the legs.
    they say their bolt on [at summitracing.com] do u you think i could bolt it to the hart top bolts, then the 2 side bolts to where the old seatbelts were, then have to add the one inbetween the legs?
    this is what i am wondering when it says bolt on.

    5 points harnesses have to be mounted in a specific way in order to work. In drag racing they check to make sure they are correct. You have to mount the crotch belt behind the seat in order for it to work correctly. If you dont you can be seriously hurt by mounting straight down. The two shoulder belts have to be mounted at least a couple of inches behind the seat on the floor, and the lap belts need to mount to the floor close to the factory locations. They check that kind of stuff in tech at local dragstrips, so if you have any questions, go ask on of the tech guys and they will explain to you where you can mount them to pass tech. I know you said you werent going to race, but this is the best way to mount them if you are going to use them.

    DONT use 5 point harnesses without a rollbar. The harnesses dont let you move when you are in them. What happens is if you are in a rollover, and the roof crushes in, you cant duck down, so you become the highest point in the vehicle. That is the easist way to get killed. NHRA wont let you use 5 point harnesses without a rollbar because of the dangers. If you put them in because you like the look, DONT use them until you get a cage. Make sure the cage is welded to the frame.

    Also forgot 5 point harnesses are not street legal. No dot approval.

    I also agree with Desert Dueler! With the factory belts you can lean over in the event of a roll and move away from collapsing sheetmetal. With a 5 pt harness you are held in place and immobile. If y ou dont have a cage you cant move out of the way of a collapsign roof and will be crushed or seriously injured.

    Yeah, those are supposed to bolt directly on to the factory mounts. I think they come with the accessories for this. I have a good picture of some 3 point harnesses I wanted to get, but I forgot where I saw it. I'll look for it and let you know once I see it.

    well the ones that mount to roll bars are above the head....
    so why couldnt i mount it from where the hard top bolts in, then on where the stock seatbelts are, then inbetweent the legs
    yeah i like the look too.
    and i know someone is gonna say what if u roll over, i will go ahead and say it, i do not do enough extreme 4wheelin where i come remotly close to rolling over.

    I would not mount the shoulder straps to the floor, because they wrap around your shoulders. In the event of a serious accident or rollover, your spine may compress or you could end up with a broken collar bone or even a broken shoulder blade. I'm not sure where the best place is to mount them(ie 2" or 4" above shoulders) but it should be to the horizontal bar behind the seats

    They DO Not mount above your head. They mount on the hoop bar. That bar that runs across the hoop in the middle is made for seat belts. If you mount them on where the top bolts to, when the roof caves in, the seat belt will loosen up, and allow you to fly out. I have the stock seat belts in my Jimmy when I rolled 6 times. I ducked down to move out of the way, but still got hit in the head. BTW you can roll almost anywhere. I rolled down a hill that wasnt too hard, but the rear end broke, and when I hit the brakes, my passenger front brake line snapped from the pressure. The line was braided steel. I caused me to shoot sideways across the hill, and tipped the truck over. Rollovers can happen anywhere.
