That your shoulders are higher than the seat belt anchor point is irrelevant, they put a block approx 4" (can't remember eact size) on the
seat base & you have to have 450mm (IIRC) to the seat belt point. Sometimes removing the seat squab will acheive this.
I no longer run Furore Products or Furore Cars Ltd, but would still highly recommend them for Acewell dashes, projector headlights, dominator
headlights, indicators, mirrors etc, best prices in the UK! Take a look at http://www.furoreproducts.co.uk/ or find more parts on Ebay, user names
furoreltd & furoreproducts, discounts available for LCB users.
Don't forget Stainless Steel Braided brake hoses, made to your exact requirements in any of around 16 colours.

there are two answers,
legally the harness has to be higher than a fixed height from your seat.
seriously, they have to be a little lower than your shoulders - say 1 or 2". Too low and you risk breaking your back in a crash due to your body
being thrown forward and the belts forcing your spine to compress.
OBviously you're never going to crash the car, but there are some muppets around who may crash into you.
You make your choice. Personally i'd buy some 2mm or 3mm box and weld it in to your roll bars with the seat belt mounts on them (and make sure
the roll bars are braced backwards).

Personally I reckon that'd fail. Then again at my SVA test they were happy for me to just use extra long bolts with a bit of steel tube between
the harness and the captive nut to "raise" the harness up higher......

Pretty sure that's a fail. Test dimensions as in the pic.

You see if you have 'glass seats you don't have that problem as all but sat on the floor..

so is the anchorage point the centre of an eye bolt if that's what is fitted or the base of the eye bolt where it meets the chassis?
Thanks

Common sense would say from the centre of the eye bolt hole, as that would be the point it would be when worn, but when does common sense go with
rules, so I'd go with were the eye bolt joins the fixing tube.
slightly off topic, but by nature of the shape of the MK F/glass seat, I can get as much as 25mm difference by moving the block, does anyone know what
point of this style seat they put the block on

The measurement is taken from the top edge of the block on the seat horizontal centre line.
