Hdv. SpectreCodename for Phantom III - Front Suspension. Herewith is N.Sch.4478 shewing the modified yoke piece which raises the front of the car 1.000. We have also further modified the upper end so as to enable the rebound to be increased to 4" while the bump is reduced to 3", in accordance with HS{Lord Ernest Hives - Chair}/Les.S/KW.26.4.35.
