350i Inner steering rack Joint Part?

[keynsham]

I have a 1988 TVR 350i and in my last MOT I had an advisory for play in the offside steering rack inner joint. The steering rack is a Ford Granada/Cortina PAS one I believe. It is the one which has the breather pipe between the two bellows at either end as shown below. Does anyone know if these are adjustable or will it need replacing? also, will that standard Ford part fit? I am sure I read somewhere that TVR shortened them but I may be dreaming that!!
