Bonnet Catch
The Bonnet Catch Adjustments.The striker pins may be adjusted for length after slackening the locknuts which secure them to the bonnet lid flanges. If the striker pins are too high the bonnet lid will not lock in the fully closed position.

The Front Seat.
The divided bench-type front seat fitted to later models is supported on two independent seat frames which are similar in design to the single seats fittedpreviously. Each half of the seat is individually adjustable for reach by means of a central lever which also automatically adjusts the tilt. Further adjustment to the tilt can be obtained by removing the wing bolts fastening the seat to the floor brackets and refitting the seat in one of the alternative holes provided in the brackets.

The Doors and Trunk Lid.
When closed and correctly adjusted the doors and trunk lid will be a tight fit on the rubber surround. Should adjustment be necessary, slacken the screws securing the striker plate to the body and move the plate inwards the required amount. Tighten the screws and recheck. Repeat if necessary.

Remove the Windscreen.
Remove the wooden glove box surrounds after extracting the securing screws inserted beneath them. Undo all the glove box retaining screws and with- draw each glove box from its housing. Depress the plunger in the under side of each instrument panel control knob and withdraw the knobs and ignition key, taking care not to leave any unit switched on after this operation. To ensure safety it is advisable to disconnect the battery. With- draw the three screws inserted through the face of the instrument panel cover and slacken the three securing the lower flange. The cover may now be withdrawn to reveal the instruments and lour screws recessed in the chromium-plated cheeks of the facia,one at each corner of the instrulnent panel. Withdraw these lour screws and, with a hand inserted through the glove box opening, remove the nut with spring
and Hat washers securing each end of the facia panel to the body dash. Disconnect the windscreen wiper control switch at the snap connector provided in each wire and lift the  facia panel assembly clear of the body dash. Extract the two screws securing the driving mirror and remove it, together with the bridge plate beneath it, then lever the centre pillar cover upwards by inserting a screwdriver blade beneath the bottom end. Lift the cover from the two retaining clips. Remove the two demister duct channels. Remove the small cover plate at each end of the centre pillar and extract the screws retaining the metal surround. Withdraw the centre pillar fixing screws and remove the pillar and exterior chromium strip and sealing rubbers. Remove the inner moulding round the windscreen by unscrewing its retaining screws. Press the glass towards the inside of the car, commencing at one corner, and carefully ease the sealing rubber from the metal edge of the windscreen housing.

To Replace the Windscreen on Early Models.
To replace the screen insert the glass in the rubber seal and press the screen into position from inside the car until the flange of the rubber seal can be persuaded over the exterior chromium finisher. Insert a length of string beneath the interior flange of the seal the whole way round the screen,with the ends of the string protruding about 9 inches beyond the unsealed edge of the glass. Note.—Care must be taken to ensure that sufficient clearance to insert the rubber strip is left between the two windscreen glasses. If necessary, small wooden wedges may be used to ensure this.
