This bush for the idler is from the steering section in the Rolls-Royce & Bentley parts catalogues for models built between 1956 to 1965.
If you have play in the steering linkage it could be coming from worn bushes. The Steering Linkage on these cars is quite an intricate mechanism so should be checked thoroughly.
