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 pr-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.

or characteristics of the plane. If I recall correctly the lower fuselage
has a slight twist in it. I would suggest leaving as is.

you will change the alignment of the tailplane with the mating profile molded
into the sides of the fuselage. This mismatch between the fuselage and
tailplane
will be very noticeable. Hence, the recommendation to leave as is.

correctly the TP18C Adjuster Body was adjusted to the extreme end of TP18B End
Fitting. This created a large bending moment at root end of TP18C resulting
in its failure. Europa issued mod 70 with a redesigned mass balance arm and
constraint of the TP19 Weights.

as there was no means to tighten or adjust the lateral restraining cables.
Additionally,
it was deemed that heavier tube and a stronger adjusting mechanism
were warranted.

were
affected (those delivered prior to February 2005). So, maybe this isnt an
issue for you.
