Hi Ron
Ref the double ended nut adjuster we made them along with all the linkage parts, we decided to make everything even the bottom of the steering coloum the T shaped part as every thing was too rotten to reuse. its not worth cutting corners on these parts as they are not just your steering it the brakes too so every thing made new and tested. all the threads are metric m12 and the left hand thread is m14 as not to get it confused
