Replacing radius arm ball rivets

[Steve Jones]

HT 5/16" BSF (or M8 if you want, nobody will ever see them). I've two cars with the chassis ball fixed this way and a third in production. The Trials Car was set up this way back in the early 1990's and has done, probably, hundreds of trials. Never come loose, never budged. Important thing is for the bolts to be a good fit in the holes.
