With regard to Rm{William Robotham - Chief Engineer}'s telephone message regarding the use of RAD-13 liners on all cars with fully floating servos, this does not apply to the SpectreCodename for Phantom III. VM-30 linings should be used on SpectreCodename for Phantom III owing to the splines which are a part of the lining. Hs{Lord Ernest Hives - Chair}/Gry.{Shadwell Grylls} | ||
