Trailing Arms Very Close to Seat Belt Bolt
The Doc - 12/8/06 at 04:35 PM

Hi,
having welded my seat belt mountings in as suggested by Uncle Ron and put everything together I find that within the mounting area it is almost impossible to position a bolt without this being located behind the lower trailing arm.

This isn't a problem as far as I'm concerned but the clearance between bolt head and the trailing arm is only a few mm. Has anyone been picked up on this as potential problem by the SVA man or is this just 'how it is'?

I seem to remember some seat belt bolts having very thin heads in the past. Perhaps I should hunt some of those down?

The Bolts must be the correct type of thread, rating, size and length. Mine came with the Harnesses. I usually help my self to a few spares every now and then when I visit a scrappy's
I have now found there are several different types of heads. Also they need to be the correct grading.

The lower outside seat belt fixing in the Luego Locost chassis is also the lower trailing arm fixing which are M12 bolts. I opened out the bush that the seat belt fixing pivots on to fit the trailing arm bolt. Passed SVA OK.

I will post a pic tomorrow.

I figured out this didn't work so my mount is in the bay ahead of the trailing arm brackets. I am posting some photos of my frame this evening take a look at the seatbelt mounts

Anyone else done as Wicket and used this method? Sounds eminently sensible to me. Why would we not do this as a matter of course?

I have a book chassis, and if I fitted a full-length seatbelt bolt it would foul one of the trailing arms. However, as the bit that's fouling is on the far side of the threaded part I simply cut the excess off.

The threaded part is deeper than a standard nut, and is made of a particularly tough steel, I have no concerns that I'm weakening anything.

Now I have a few mm clearance, which allows for any bush twisting.
