YOKE PIECE GIVING INCREASED FRONT TRACK (58.500") FD.{Frank Dodd - Bodies}251. BENTLEY 50. We attach hereto blueprints of PD.251, which shows the yoke piece to give the 58.500" front track required by Ev.{Ivan Evernden - coachwork} to obtain the width of front wing for the desired frontal appearance, but without raising the car at all. The yoke piece can therefore be used with the existing Girling brakes, the only modification being a longer rod between the operating wedge and the intermediate lever on the yoke piece. The increase of length of this rod is 0.870", or actually 1.00" more than the original rod. Opportunity has been taken to stiffen up the yoke piece by a general increase in sections where possible, both because of the increased weight of the B.50 as compared with the B.111. and also because various experiments on B.111 have shown that a stiffer yoke piece is an advantage from the point of view of the rubber suspension bearings.
