X.5310 CENTRAL CHANGE WITH SERVO. X.5770 X.5370 Re. Mr. Stent's memo. I had looked at the present box on the car here, and came to the same conclusion - i.e. that there are two ways of arranging this, the more hopeful being - (1) the servo on driver's side, and hand brake shaft just behind centre of change speed lever tower, passing to the left side of box. (2) The alternative seems to be to put the servo on the left side as in the four speed box, and leave the hand brake such as on 7-Goshawk(Aero Engine)(Codename for 20HP Car / Aero Engine after Kestrel(Aero Engine))-2. (1) seems the easier, quicker, and better but if not perfect try (2). R. {Sir Henry Royce} | ||
