Superformance Harness mounting

[justbetter]

Ok all you Superformance Owners,

I have a 2003 MK3 Superformance here on OZ, and am wanting to mount a 4 point harness.
Now the base points are fine but trying to locate and mount the above sholder locations points are a bit of a problem.

Im not sure if i mount to the roll bar ( or through ) if it is strong enough or crush resistant enough.

Or where there may be other points apart from adding a seperate bar between the two forward roll bars and mount there.

Or if it is safe enough to mount them to the bolt mount that attaches the third rear leg to the forward roll bars, this location seems to high.

Look forward to your help, Pics please.

Regards Garrett
