Waller - Head of Chateauroux}10/JH.29.6.38. 7.B.V. Bentley.III. Silentbloc bushes in front suspension. The silentbloc bushes in the lower suspension levers are at present made to special dimensions and expansive. Bushes of a standardised size have been obtained for test, will you please fit them to 7.B.V. Either 5/8" bolts or sleeves on the existing ½" bolts will be required and washers to take up end clearance. The washers should be the full diameter of the outside of the silentbloc, in order to reproduce the clearance which would obtain with brackets of the correct width.
