The Libra utilises the front seat belts from a K Series Rover Metro The mount to special reinforced areas within the monocoque

Assembly

The front seat belts of the K Series Rover Metro are handed and therefore it is important that you use the driver's side out of the Metro on the driver's side of the Libra.

It is easier to tell which side is which by starting the assembly from the outside bottom mounting. This mounting is made on the K Series Rover with a loop of the seat belt slides along a bar, which is attached to the car. This bar is retained on the Libra and fits as shown in the diagram. Start by drilling the 13-millimetre clearance hole in which the joggle part of the bar will fit.

Due to the angles involved it is easiest to put a small pilot drill through the position first and then follow through with a 3-millimetre drill. A certain amount of filing will be necessary to enable the bar to fit through the sill. Fit the bar through the sill and using the bar as a template drill the front hole half an inch clearance 50 millimetres from the floor of the car. It is necessary to hole saw yourself a 60 millimetre diameter approximate hole in the sill to enable you to fit the seat belt mounting plate T0630 behind the sill to locate the seat belt rod. Repeat the procedure for the other side of the car.

Now fit the inertia reels to the bottom corners of the rear box in the position shown on the diagram. Before fitting the inertia reels it is necessary to drill out the threads from the inertia reel fixings to a clearance hole to enable the inertia reel to be fitted from the inside of the car. Be extremely careful when drilling out the threads of the inertia reel mountings as it is extremely easy for the drill to snatch. Mount the inertia reel with a seat belt mounting plate T0630 behind the back box. Access is obtained through the hole already cut in the back box. Repeat the operation for the other side.

On the standard Rover Metro the centre lower positions of the seat belt mountings are joined onto one bracket. On the Libra this bracket is not used and it is necessary to remove the separate part of the mounting from the bracket by angle grinding or filing the outside face of the rivet.

The brackets are attached in the position shown on the drawing with a special bush T0631 between the bracket and the tunnel. Drill a clearance hole in tine position shown on the drawing and working with an assistant hold the seat belt mounting bracket T0630 on the inside of the tunnel tightening the bolt from the inside of the car.

The top seat belt mounting is mounted as in the K Series Rover Metro to the bush already located in the monocoque in the side quarter panel. Use special bush T0632 to space the standard mounting away from the monocoque so that protrudes through the trim panel. You need a special bolt 50 millimetres long 7/16 UNF has to be used in this position and not the standard top mounting bolt.
