E {Mr Elliott - Chief Engineer} /Ev. {Ivan Evernden - coachwork} 11/MN.2.2.37. 1049 646 Rear Anti-roll Bar for use on Wraith II with Phantom III Rear Axle. Until we have the proper rear axle for Wraith II with the 1.650 hypoid and road springs with .5 camber, the rear of the car will be riding .8" high, and there will be a foul between the back axle centre casing rear cover and the anti-roll rod. We suggest that on the cars having the Phantom III axle, until such time as the axles are changed, be fitted with an anti-roll bar which is set back .550". The position of the roll bar should be so set that the plan of the bend in the roll bar is horizontal when the axle is passing it, - the scheme shown on LeC.5501 herewith.
