Steering shaft leak

Hi
The latest problem on my Williams 1 is the steering shaft has a leek. :-(

Is it the case that you have to change the whole rack to fix that?
Does anyone know the best place to source a replacement?

cheers
Nick

It looks like the racks have been discontinued, :-k does anyone know where I can get hold of one or any ideas of what to do next?

either have it rebuilt or get a pattern part, where abouts is it leaking?

Thanks for the info.
I wasn't working on it so not sure exactly where the leak is except at the steering shaft.
already tried a leak fix fluid in it, but it didn't work. I hear that usually these things can't be fixed properly and need a new rack.

One person has suggested that I should get a new one that is similar to the old one and change the tie rods to fit, is that a good idea?
