My engineer explained to me that it needs be a 3mm plate at least 175mm2.  The thread must be at least as deep as the bolt is wide.

I used a length of 3mm plate, quite long (well over 175mm2) and cut the pillar to get it in.  If you havnt got the hood lining in, I believe that you can slide it down the pillar from the top.

A small cut at the base behind the rubber is worth looking at for this.

Just my experience, but check with your engineer.

175mm2 doesnt sound big enough from what I was told when I did mine. The plate that I put in the pillar was 55 x 70 mm giving 3850 sq mm by 5mm thick. this is the minimum size that I had to put under my seats and also for the bolt oints to the floor.

I got the grade 8 seat belt nuts and welded them to the back of the plate first, then cut the appropriate slots in the side of the pillar to fit.

I then drilled 4 holes in the pillar around where the seat belt bolt would go through, this was so that I could weld the back plate into place.

Placed the plate in place, welded it up to the pillar and then filled in the slot after the engineers was happy that I had done the right thing.

Hope this helps.
