Undertook repairs today and finally could refit the cover.
There were three issues.
1. Remove the height adjuster and bent the flange. This needed heating and then smacking with a hammer and lump. See Page 8
2. Bend the adjuster so parts were parallel

3. Having done the above it now didn't align with the hole in the wheel legs so I elongated the hole with a file.


4. The above meant the adjuster didn't move as the bolt fixing it to wheel leg went up against the adjuster body, so the adjuster body was bend outwards. Note the small amount of light between the bolt head and the adjuster body frame.

Finally the adjuster cover, having been repaired was refitted knowing that the adjuster will not impact upon it.
