And how did you open and re-close the lock tabs; the radiator makes access difficult on mine?
The bracket with the two bolts through it ... is that the same one that also holds the track rod ends?
It is the bracket that holds the track rod ends.
The locking tabs on the bracket are more accessible when the track rod ends have been unbolted from the bracket. I used an old screwdriver and hammer to bend the tabs back. I didn’t flatten them, so I was able to use pipe-grips to bend them back.
Access is limited, but I didn’t struggle too much.
Take care to replace the spacers back the correct way up when you put the sleeve back on. They fall to the floor when the sleeve is removed. They have a flat face and a slightly curved one.
