Thanks Eric for a detailed and comprehensive reply!
I have passed on the kit to a friend, who intends to complete it and I am trying to get him started.
This kit was delivered in 2002 and has the cables as standard, so I believe it is pré-mod 70 and so the arm will need replacing.
I do believe the slight misalignment will not result in any noticeable effect, but that will be up to the new owner to decide- your recommendation is noted and I do agree with you.
I am not sure if I understand what you mean by saying realigning the bush will have a detrimental effect on, as it seems the bush will only move a tiny amount and into the correct position..?
As the factory is no longer responding to requests, we will have to try to make up parts for the required mods, (57, 70, 72, 73 and 74) so any info such as photos, dimensions and material specs and other info not available in the modification
instructions, or help in obtaining the parts, would be immensely appreciated.

it was deemed that heavier tube and a stronger adjusting mechanism were warranted.

an issue for you.
