Right guys,
I have got a safety devices roll cage (rear cage - detachable diagonal). I have got it in but I not 100% sure how to bolt it in.
For the two bars that go on the rear wheel arches, I have to bend the plates to the right curve. Then drill the holes through the arch then put the plates under the wheel arches and bolt them together (sandwich style).
Is that right? It seems ok. (Bending the plates seems the hardest bit)
But,
The bars that are in the rear bins seem alot harder to do.
Am I drillling through the hollow sills?
If I bolt through the hollow sills wont they crush?
(sandwich style again)
Am I missing something?
Cheers,

Ps I have to sort this by Friday as Im going to Italy!! :erm:

Bolt it up and it'll bend to the right shape as the bolts tighten down. Dont forget to put the bolts thru from underneath and have the nuts on the inside. Drilling the holes in the pockets is the hardest bit, use a self punching centre punch to make a dent for the drill bit to sit in else you'll find the bit wanders all over the place.

Just bolt it up, they wont squash because of the sandwich plates spreading the load.

IIRC It should only have hollow sections it oversillS have been fitted, even then it should only be at the most 10mm.
Make sure any plates you are using have all the corners rounded off. The spreader plates should really be welded in place.
Fit the bolts with the threads inside the body.
Remove any carpet that may be in the way.

Prawn, a decent cage should have come with all the fittings you need as they are just as important as the cage itself. Only as good as the weakest link and all that. If you do just get the bolts from the hardware shop make sure they are the correct grade of steel, as they need to be strong enough to resist at least the shells tendency to twist. If they can't cope with that then they'll get weakened quite quickly in use and when you call upon them in a crash or whatever they may just snap. Any old bolts WON'T do.

As Dan says it MUST be fitted corectly, a badly fitted cage is probably worse than none.
Personally I think that those cages that bolt in to the seat belt mounts are dangerous

thanks guys, id NEVER use a cage that bolted tothe seatbelt mounts, that just stupid :S:S:S
the cage i have is second hand, and came out of a sprint car and hence has no fittings, as i was just given the cage alone
i can get decent bolts from the local store, tehy sell every form of nut and botl imaginable
what thickness should the plates underneath be?
