SS100 Build Manual (Export Edition)
1no. Length of Sticky backed Sponge Rubber
•
2no. aluminium load spreading plates
•
Note: To fit the screen the builder will need the help of a second person. Before starting ensure that the
car is level, particularly transversely.
8.2.1 Mirror and aero screen brackets
Firstly fit the side mirror brackets and aeroscreen brackets to the windscreen using the screws provided. The
aero screen brackets fit with the spindles facing outwards and the longer spindles on the outside.
8.2.2 Windscreen positioning
Cover the scuttle area where the screen will fit with "low tack" masking tape to protect the paint work. Place
the screen in position on the scuttle and maneuver it so that it is parallel with the dash face and level (use a
spirit level), and positioned as per figure 14. A length of wood notched at each end giving the 42 1/2"
dimension is a help. This dimension is important if the hood is to fit correctly on the screen and for the wiper
spindles to be in the correct location.
8.2.3 Fixing windscreen
Now check that the screen base conforms satisfactorily with the scuttle face. Any gaps should be no more
than 1/8". If the gaps are greater, mark the high spots with a chinagraph pencil, remove the screen to a carpet
covered bench and carefully file away the high spots. Re-offer to the car and repeat until the fit is
satisfactory. (Recent experience has been that no filing is necessary). Position the windscreen again and
when satisfied drill the 6 holes 6mm through the body for the mounting plate screws. Secure the 2 mounting
plates to the body with the M6 x 25mm domed headed countersunk stainless screws and mudguard washers
or alloy spreader plate & nyloc nuts.
8.2.4 Wiper spindle holes
The next operation is to drill the holes in the scuttle for the wiper spindles. It is necessary to drill two
11.5mm holes through the scuttle to the back of the dash using the holes in the screen as a guide. Do not try
to drill pilot holes and open the hole out gradually. Putting the full size drill through in one operation using
the screen holes as a guide minimises the tendency of the GRP to crack and spall. It also helps if the drill is
slightly blunt, then it has less tendency to "grab". When you offer up the drill, have the second person
standing alongside the car to ensure you are drilling perpendicular to the screen. Where cracking and spalling
(hopefully minimally) has occurred and touch it in with a little body paint. Open out the holes on the inside
of the body a little with a file to enable the wheel boxes to fit well.
8.2.5 Screen seals
Remove the screen and fit the rubber sealing strip to both the front and rear faces and hold them temporarily
in place with small pieces of masking tape. Cut gaskets for the two mounting plates from the 1/16" rubber
sheet. Sticking them to the inside of the screen mounting plates with contact adhesive (Evostick or similar)
helps to keep them in place. Remove the masking tape from the scuttle.
8.2.6 Re-mounting screen
Apply sealant sparingly to the underside of the screen rubbers and a little washing up liquid to the inside of
the mounting plate gaskets. This allows them to slide easily without marking the paintwork. Remount the
screen and fix in position with the M6 stainless screws. Clean off any excess sealant with white spirit.
8.2.7 Wiper motor and drive spindles
Fit the wiper spindles complete the wheel boxes, rack and wiper motor as a unit, placing two of the four
7/16"UNF nuts on the spindles between the scuttle and the screen, and secure the wiper motor with the "U"
bracket on its mounting plate with 1/4"UNF x 11/2" bolts and nyloc nuts, the drive tube should run from
the motor towards the left above the short stay before turning back towards the spindle wheel boxes. Place
the other two 7/16"UNF nuts on the spindles after they have passed through the screen. Adjust the position
of the wheel boxes so that they are as far from the dash as possible (space for the ammeter and oil pressure
gauge is at a premium), and secure the spindles from the front of the screen with the two remaining nuts.
