You need two eye bolts through the bulk head behind the seats, at the same height as your shoulders, don't be tempted to mount the shoulder straps over the back of the seat and down to the floor- this won't protect you in an accident (unless you loop them over a harness bar).

For the drivers seat, you can fit an eye bolt in the existing seat belt mounting point behind your right thigh. For the other side of the driver's seat you'll need to mount an eye bolt through the floor- try to mount it through the area of the floor that is double skinned for extra strength.

Hope that helps, I'll try to see if I can find some pic's to help :thumleft:

great stuff

my thoughts on fixing was

rear fixed here

Image

door side fixed here

Image

and fuel tank side fitted here original seat fixing as celica seats dont use this

Image

the whole point is for them to fit through the holes in seats nicely as seat belts are rubbing on leather and damaging it

That rear fixing is too high, it has to be just and only just below below where the belt goes through the seat

I'll be honest- I don't think that's the best idea, not convinced that little hook is strong enough to trust your life to in an accident 8-[

Personally I think you need proper solid anchors for your shoulder straps, and I don't think there is anything on the rear bulk head that is already there and up to the job. If it was me I'd be drilling two holes through the rear bulkhead for each seat, and using eye bolts into decent size anchor plates mounted engine side. That's how I did mine, and exactly how I plan to do my next car as well :thumleft:

yes but immediately after the article is this...

From: Simon Tremblay ([email protected])

I write you about certain modifications articles that I found on the
site.

(...)

There is also something that is always on my mind and it is about the
safety of those that installed safety harnesses using the attatch point
behind the driver seat similar to the baby seat attach point. It is
extremely dangerous to do so and someone using this attach point put
it's life in stake! This point is NOT strong enough to sustain the force
of a crash. The information article by Marcus Hall is wrong in that way
of thinking. The article should be corrected. I found out about this
when I cut that part away to install my racing harness properly. It is
only thin sheet metal and will tear if a crash occurs. I cut it away to
install a thick steel bar behind the firewall to attach my harness.

just becuase someone has posted it in a guide does not stop it being rediculously dangerous and them being irresponsible.

Ash has said the only true way, then confirmed by Bob :thumleft:

Drill through and bolt it up, you can weld it if you want, but not required.

And you'll need one for each anchor point, so if fitting harnesses to both seats you'll need 4 for your shoulder straps :thumleft:

Yes, you must use one per strap. I have also put a flat plate on the inside on my ones so the bolts clamp a much bigger area.

Yes thats right, but two straps would be better. I would also not buy anything off ebay, they will come from China and be crap, you must buy the best, its your life they could save
