The original recommendation of the Division, whichwas circularized among the universal-joint car and motor truck manufacturers, specifieddimensions for the outside diameters of the universaljoint companion flange in order to permit the transmis-sion designer to lay out the gearshift rods so thai thejwould clear the companion flange. Criticisms received,however, indicate that the large number of different typesand sizes of companion flanges would not permit specifjing outside diameters without affecting individual design.
