| (2) REAR APRON. Similar to that of J.3. SHOCK DAMPERS. Same as for J.3. FRONT AXLE. Scaled down from J.3. but with axle control. BONNET. Rivetless in aluminium. All fittings to be same as for J.3. DASHBOARD. Cast aluminium with the same shape of pot and depth of pot as J.3. Universal type. STEERING COLUMN. Same as J.3. Two angles are provided with the same column length. PEDALS. Use J.3. pedals but spaced as on N.sch.3344. INSTRUMENT BOARD. Switch and controls to be the same as J.3. All other instruments to come from one source and to be in a patch in the centre of the board. CENT. CHASSIS LUB. Use J.3. pump. WIRING. All junction boxes and adaptors to be the same as J.3. FOOTBOARDS. Unframed by the use of Plymax or framed with a metal angle. COACHWORK. Due to special treatment of the frame springs and exhaust pipe the rear cushion is entirely between the frame side members. On max. two wheel bump the axle casing compresses the cushion from below anything up to 2.000 ins. The axle diameter is therefore of great importance. It should be as small as possible. SUGGESTED STOCK BODIES. (1) Four door six light saloon on 'D' steering (see N.sch. 3346). One spare wheel at side. (2) Four door, four light saloon on either 'D' or 'E' steering at customer's request. One spare wheel at side. | ||
