Nylon screw fit lower steering bush. The nylon bush is the best upgrade for all TR7/8's. It is a once only fit that will remove all the play in the column and never wear out. Unlike the the rubber or poly bushes this nylon bush will not be cut by the bulkhead so will never need changing and always give positive steering shaft location. This bush is a direct replacement to remove the play in the standard rubber or plastic bush. Fit and forget, never to be changed.
