If these are the pipes you are having a problem with.........
I found this on an old thread on the forum.....so it may be worth seeing if this company still exists.
“Just an update, ready made pipes arrived from Power Steering Store situated between Coventry and Solihull complete with o-rings. I was happy with the inclusive price of £30 for both pipes, four seals and postage and they arrived the following day.
Fitted with only moderate swearing once I found it was much easier by taking out the two rack bolts and pulling that forward slightly.”
It refers to part number 4 below that is no longer available ref RealOEM
Hope this helps you...
