Three or four point harness's can be used on the road providing they are correctly fitted as per manufacturers instructions.(my boss's dads Series 2 Landrover has four point harness's in)
On your jago this will most likely involve the fitting of a suitable steel tube across the roll over cage at the correct height to mount the shoulder strap mountings. If I remember correctly as this is then classed as structural so will need to be welded the the roll over cage.
The mountings for the waist straps will also need mounting to the main structure of the chassis not to the body or floor. This may be the original lower mounting poits for the seat belt ie the lower mount for the spool on the bottom of the roll cage and the centre mounting point which the locking arm for the belt went on.
Like I say check the instructions from the harness manufacturer and if needed have a word with your MOT man after all he will be the one testing your vehicle.

when i took me jeep for m.o.t i told the tester i had not tested it earlyer as i was trying to get seat belts for the jeep.And he said if i took it to be tested with no seat belts it would have passed as they m.o.t them on the donor car and if its b4 the date when seat belt were made compsury when the car was build from then you dont need seat belts in at all and the cops cant do anything about it as i have been pull up and i told the cop that cos its m.o.t as wot the donor car plate was i dont have to. or need to wear them and he was not pleased so i bet hes will now be looking the data up for when he comes acroos me again.till then i had last laugh.
thanks for all that, my donor plate is 1972, but i had a mk1 mini last year which was a 62 and that never came with any belts at all, i think the cut off date is 64 for that one, plus i want to fit something, having never driven rwd before i don't fancy flying out the side of the jeep first time i launch it out of a corner, regarding lower mounts i think i can use the roll over bar lower mount on the out side, and the original mount on the inside for both seats, and for the top i am hoping i can go over the seat, and down at a fairly steep angle through the floor and tie up with the chassis somewhere, if i use an m12 bolt and go right through the chassis and use a spreader plate i would of thought that would be structural enough for mr mot, thanks again for your input, you have all basically built this jeep as i was clueless when i started
Hi just a little more on harness fitting. Techsec is right in stressing that you should read the manufacturers fitting instuctions very closely. Which is what I found i needed to do with JKR's 4 point harness fitting. Don't forget the point in fitting the harness belts, or any belts for that matter, is your safety not looking to score points against 'Mr Plod'.
So, fitting the belts to the original belt mounting point on the Geep will mean the car should pass its MOT but, and heres the safety issue, they won't comply with the manufacturers fitting instructions!
Why?
You will firstly, as already stated, need to weld a substantial tube horizontaly between the roll bar hoop uprights. Into this you should drill and fit threaded inserts for the top belt mounts/straps. These must be suprisingly close together. Maybe 6" or less? This is per seat belt and refering to the 4 point fixing. At the bottom end you will need to fabricate mounting brackets to extend forward from the 80X40 box section which links the bottoms of the roll bar ends together (the rail beneath the floor). Finally, these should be a maximum width apart (per belt) of 16.5", or they are on my instructions.
I know this all sounds very involved and tedious but thats not what you would be thinking when the time comes to testing them in a real emergency!
I can photograph the fitting of my own harness set-up if this clarifies my instructions - just ask
Cheers

I can confirm the 4 point harness setup, my Geep was built by a chap who was into eventing and he built it with a lowered roll bar and the horizontal welded behind the seats.
I had 4 point harness fitted, which I removed when my Huntmaster seats fell apart, now using standard belts with high back clubman seats, these have to go! I loved the security of the harness and as my grandchildren often travel with me they are perfect - so my next investment will be slotted buckets!
