Folks
I now have a harness bar fitted to my car. I have included 3 photo's of the bar showing:
002 - the detail of how the bar is fitted to the body, using the upper B-pillar OEM seat belt pivot bolt, braced back to the lateral bodywork brace
004 - showing the harness shoulder straps looped over the harness bar
006 - showing the harness retaining fixtures to stop the harness moving laterally - these are sized for a 3" harness
I have not shown any detail of the laps belts. On the outside of the seat, an eye-bolt has replaced the 7/16" UNF bolt that locates the seat belt tensioner to the base of the B-pillar and the lap harness has been clipped into this eye-bolt. This requires a 19mm hole in the plastic trim at the base of the B-pillar (a 19mm blanking plug in grey plastic is available from any auto accessory store to dress the hole when you eventually sell your car). On the transmission tunnel side of the seat, a 1/2" hole has been drilled thru the tunnel with a 50mm x 75mm 4mm thick anodised steel plate on the underside of the car and the eye-bolt tightened thru it. There was no other option to adequately (from an engineering perspective) fit the eye-bolt which needs to take a load of 100kg (ie: my bodyweight) when being decelerated by up to 8G, as the rear seat slider bolts are not 7/16" UNF threaded (they are metric and we could not source metric eye-bolts). It will be necessary to remove the eye-bolt prior to vehicle sale and replace it with a plain black headed 7/17" UNF bolt prior to sale.
The bar was engineered by TrackArt Fabrications in Bayswater North (Melbourne, Australia) and they have made a jig and can supply these bars to order. Contact Andrew on +61 416 1310. They are located at Factory 13, 6-7 Nicole Close, Bayswater North, Vic 3153 and they can be found at

Express Parcel post to the USA is around US$140-160 - speak to Trackart for pricing on the harness bar. For supply into the USA, please note that these devices are supplied as-is, for off road use only. Installation will be at the purchasers risk.
The jig has been built symmetrically, with LHD and RHD vehicles in mind.
