The crush tube is definitely gone then, its not in the old arms or with the old hardware either so I must have accidentally turfed em. If you've got the measurements of one it shouldn't be too hard to find a piece of tube to make them up. 

With the double-wide brackets it actually looks pretty straight forward to cut the mounting plate off then mod them to suit a standard sway bar. Got nothing to lose anyhow because I have the stock ones sitting right there. Time to do some geometry.. or well time for chatGPT to do some .

So - to change the standard castor positive by 2 degree, the mount needs to be picked off and welded 20mm forwards of the original sway bar mounting position. 




I have a science experiment to do tomorrow!
