350i Steering Rod bulkhead bush

[Pigboger]

The steering on the 350 is feeling a bit vague as you begin to turn the wheel. I have replaced the rack and everything else including the suspension seems fine. I suspect the bulkhead bush is a little tired. The steering rod appears to be about 3/4 inch in diameter. The car is 1988. Is there a replacement bush available or modification ?
Non power steering.
Many thanks in advance.
