SERVO JAGGERS .-X.3855. X 8370 X 5370 Apparently these hardly exist on the 20HP. perhaps because of the flexibility of the cross shaft between pedal and servo. The Phantom rubber washer is so good and necessary that it must be used. I did not stop it (having suggested the flexibility in the first place as a cure) but asked for it to be in steel instead of rubber for permanency, and I thought it was easily possible, but if DA.{Bernard Day - Chassis Design} or Derby cannot find a design I will try. In the meantime don't let cars be used without this, to me, very necessary fitment. It worked like a charm on 7.EX. R.{Sir Henry Royce} | ||
