RHD Bentley Models
From 1977 to 1984 (VIN 13000 approximately) all RR and Bentley models were fitted with the same steering rack.
From 1984 Bentley started to fit a stiffer steering rack to all of their models to give them a sportier feel.
The only exception to this rule is the Bentley Continental (Corniche) so please refer to the RR section if you have a Continental.
