non adjustable harnesses made adjustable

Bloke at work has given me some willians 6 point harnesses that are his old racing ones. They are out of date but in perfect condition. I am assuming they will be okay for iva. The main leg straps are non adjustable. They have two plates that trap the belt and effectively prevent adjustment. Fine for a racecar, not so much a road car. Has anyone every converted a set?

Can the belt be fastened without the crotch straps? I don't think I would fit them for the road.

Why risk an IVA failure over a possible bodge, to save some money

Plus by altering a seat belt, surely you are putting your lives at risk?
I would not do it!

a picture tells a thousand words, but as already stated, just don't use the groin straps.

I was just going to use the lap belts and the shoulder belts. 6 points seems overkill.

As you can see from the crappy image is one of the lap belts. It doesnt have a adjuster like the shoulder belts. It merely has two metal brackets that clamp the belt when you tighten up the chassis belt. If I clamp the belt at its longest setting and then place some sort of adjuster in the system I might be able to make the belts more useable without cutting or chopping them.

Can't you just make them the correct length before bolting them up? That way they won't need adjusting.

I can certainly do this but what if the iva man is fatter than me? Will this be acceptable at iva?

The IVA test manual mentioned the following in relation to seat belts. Therefore, you cannot lock them in place before IVA. I went through two second hand sets bought off here and e-bay before I ended up with ones where the adjusters were in the right place (not as expensive as you might think, because I sold them again on here and got my money back) - some have a second adjuster on the shoulder strap that fouls the hole through the seat backs and ideally you need the adjuster on the lap belt to be at the buckle end and not the mounting point end.

For a static seat belt there is a manual adjusting device:

accessible to the wearer when seated
convenient and easy to use
capable of being tightened with one hand.
