Seat belt anchorage points.

[Donunder]

The Arntz that 750HP has been inquiring about finally arrives in Brisbane (Australia) this week.

To compliance the car for Australian registration certain modifications have to be made, such as new headlights that dip to the left, a reversing light activated by a gearbox switch, and possibly a high level brake light, etc -- all pretty straight-forward and understandable stuff.

What is a bit hard to take however is that the car's lovely 3" wide racing harness has to be ditched in favour of a retractable lap-sash seatbelt system. This will necessitate a floor mounting for the lap part of the belt either side of the seats with the tongue-clip on the outer or door side of the seats and the fixed mount adjacent to the transmission tunnel. The inner upper mountings, the shoulder sash part, are to be located at shoulder height between the seats. The retractor mechanism can either be mounted at this point, or the belt can pass through a runner and the retractor mechanism can then be affixed to the floor.

With the fuel tank being mounted up high behind the seats, how have other Arntz owners tackled this installation? Is there a substantial frame mount available up high on which to mount the retractor or, because of the fuel tank's proximity, is it preferable to mount it on the floor? At 6'5" I'm planning on using ALL available space behind the seat (and then some!) to be able to fit into the car, so I guess I'm really hoping that the bulky space-consuming retractor roller can be located up high between the seats.

Any information, and if possible some photos, on lap-sash belt installations, particularly those with high mounted fuel tanks and high mounted belt retractors, would be very much appreciated.
