Fitting a Split Screen
Using the centre pillar grommet as a template, mark the centre pillar drilling positions as far forward as possible on the scuttle centre line [See sketch 1]
Drill the necessary clearance hole, make a simple support bracket [See sketch 2] and fit the central pillar and grommet using a set screw of the correct thread size and length.
Using the side pillar grommets as templates, mark the side pillar position cut outs as far back as possible on the scuttle. Trial fit the glazed panels in the centre pillar channels, using them to mark the side pillar cut out positions equal about the centre pillar. [See sketch 1]
The supplied side pillars will not lie at the same angle as the fitted centre pillar without substantial grinding of the pillar mounting faces, enlargement of the scuttle cut outs and shortening of the side pillar legs in the engine bay. The amount of machining required can only be determined by regular trial fitting. All machined faces of the pillars should be sealed with clear lacquer on completion.
The supplied side pillar mounting brackets [designed for the standard flat screen] should be modified or replaced to suit the angle of the side pillar mountings in the engine bay. [See sketch 3]
Bolt the side pillar support bracket base plate, complete with packing plates, to the pre drilled chassis mountings. Offer the new R.S.A. upright to the side pillar lower legs and base plate, mark out for new/existing drillings.
Remove the side pillars, drill the lower legs and new R.S.A.’s as previously marked, reassemble the complete screen with the R.S.A.’s bolted to the side pillars. Tack weld the R.S.A. to the base plate while in position, unbolt and remove the side pillars, remove the brackets and complete the welding of the R.S.A.’s to the base plate.Assemble the complete screen and brackets, remove or reduce the depth of the packing below the side pillar brackets until the screen is pulled firmly down on to the scuttle.
When the desired screen position has been achieved, loosen the end pillar brackets sufficiently to remove the glazed panels, run a silicon seating bead down the channels of the pillars and make the final assembly
Trim the rubber strips fitted
to the glazed panel to suit the pillar grommets, seat the strips to the grommets
and scuttle with silicon.
Cautionary
notes
1] The windscreen assembly comes complete with countersunk set screws for securing
the outer pillars to the glazed panels. These screws are of different lengths
and must be used in their correct tappings, which should be blown clean to avoid
damaging the glass.
2] The dimensions given are as per a specific car an may very slightly on other
builds.
