Agree Gee Ltd Terry Foxen is first choice, we have a gentleman who is using Techniques to fit a new steering box supplied by Terry.
I also know of a gentleman who has converted his steering box to right hand drive and may have spare parts.
Thank you! I've emailed GEE and am waiting for a reply. Can you please ask your friend if he would be open to an email exchange with me regarding what parts he has? I can PM my address to you.
