| Rm.{William Robotham - Chief Engineer} RUBBER BETWEEN AXLE AND SPRINGS. Any 'A' Series chassis requires new axle brackets to be correct to design. The existing brackets lower the rear of the car .450 and also reduce the buffer clearances. Lowering the back of the car makes the visibility worse. The correct height of the rear of the car can be obtained by various methods. 1. New axle tube brackets. 2. Alter spring camber .450". 3. 100 lbs increased poundage rear springs, giving 6 1/2" initial deflection. We recommend that the alteration in height should be made by the road springs. The other features required are small, viz., rubbers, plates and bolts. Rm{William Robotham - Chief Engineer}/Les.{Ivan A. Leslie} | ||
