The arm that normally projects into the car so the door mirror can be adjusted<br />

from inside the Metro has to be removed using a hack saw at a point<br />

approximately 10mm from the spring retaining washer. The wing mirrors can<br />

not be adjusted from inside the <strong>Libra</strong>.<br />

Refer to drawing No 17. Where the wing mirror mounts to the door outer<br />

panel mark the centre of the boss and pilot with a small drill. With a Ø30mm<br />

hole saw, drill out the central part of the mirror boss. Two Ø10.5mm holes<br />

now have to be drilled on approximately Ø41mm centres to enable the<br />

mounting tubes to come through the outer skin of the door moulding. When<br />

drilled these holes just break into the surface of the Ø30mm hole previously<br />

hole sawed. The wing mirror can now be positioned on the door with the two<br />

mounting bosses projecting through the door and being accessible from the<br />

inside of the panel. It may be necessary to slightly adjust the Ø10.5mm<br />

clearance holes depending on the exact size of your particular moulding.<br />

Place one of the door mirror mounting sleeves T0522 over one of the<br />

mounting boss tubes projecting into the car and with a 15mm long set bolt and<br />

large 6mm washer, secure the wing mirror. The other door mirror mounting<br />

sleeve can now be fitted over the other tube and secured in a similar manner.<br />

Tighten both bolts equally to secure the mirror to the door shell.<br />

The door inner frame complete with its glass can now be reassembled to the<br />

door shell using the four stainless steel 6mm screws and special washers.<br />

Attaching the Door to the Monocoque<br />

Refer to drawing No 16. Pilot drill the centre of the indent on the front of the<br />

doors where the door hinge bushes T0510 fit. Open out these holes to<br />

Ø13mm. Press fit the two door hinges bushes T0510 into the door outer shell<br />

and tap home with a suitable soft mallet.<br />

Using door hinge bottom T0512/3 as a guide, locate the two indents on top of<br />

the sill which correspond to the two larger holes in the door hinge bottom<br />

plate. Spot these two centres with a pilot drill. Open out these two holes to<br />

Ø6mm clearance. Bolt the door hinge bottom T502/3 to the doorsill through<br />

the doorsill to door hinge bottom spreader T0504 using two Ø6 x 25mm long<br />

socket screws and large 20mm washers. The door hinge bottom should now<br />

be adjustable in all directions around the 6mm bolts by loosening the screws.<br />

Using door hinge top pivot plate T0508 as a guide, find the corresponding<br />

three indents in the vertical part of the door aperture in the monocoque and<br />

spot the holes. Open out these holes to Ø6mm clearance. Bolt T0508 to the<br />

vertical face using three countersunk socket screws 25mm long washers and<br />

Nyloc nuts. Mount the door hinge top pivot T0506 to the top of the door hinge<br />

plate T0508 with door hinge top spreader T0509 on top using two Ø6 x 12mm<br />

long socket cap head screws and washers. By slackening the screws, the top<br />

pivot should now move around freely about the Ø6mm screws. Remove the<br />
