Tony -
I am sorry I can't offer the information you seek. I agree that the rivets are
a problem; I solved it in my case by fitting them at 45 degrees - see:
<http://www.rowlandcarson.org.uk/aviation/europa_435/201203.php> and scroll down to day 21
In your situation, I'd be inclined to order a new link rod etc and re-make it as
I'm not sure that there would be enough meat left to support another rivet.
While you're at it, you may also fall foul (!) of another issue - you'll see my
solution to that on this page:

Tony,
My to-be-inserted length is 16.1 +/- 0.2 mm.
Thank you for bringing up the potential issue..

Subject: | Dimension Requested for Trim Tab Link Rod Fork insert |
Tony, have a look at the link rod between the servo and the bell crank
I had a long hard look at it and ended up shortening that link rod about
2mm, trimming the plastic will fix the issue, mine only needed about 2mm
total to gain
The required clearance, I filed a bit off each one and problem solved, prior
to that 2mm it would foul
And try to push the servo up at full travel
Hope this helps, it may be another way to attack the problem
Regards

Gidday,
Well, it seems my Trim Tab Link Rod, TS05 is conflicting with my plastic
forks of the servo, like many others. I think I have to eat humble pie here.
The issue is that the vertical of the two rivets that hold the insert AN490
HT8P in position, its head is the culprit. It looks like to me the easiest
fix is to take a little of the fork excess plastic away, but there isn't
much, and any finer adjustment needs to be made by removing the offending
rivet, and repositioning it. Thats my current plan, and to that end I'd like
to ask what the length of the insert is that is within my T bar tube. I am
thinking of removing the offending rivet and repositioning 45 degrees
offset. I would like to double the spacing that exists between the current
rivets, in side elevation, for the placement of the next one, so I have
double the metal since I have half the offset, as the holes from the removed
rivet will have created a wall weakness. Still, there shouldn't be a
ridiculous amount of load on these, and the second one is probably more of a
secondary means of attachment, aviation double check anyway.
If anyone has not constructed the T bar, can I please ask for the insert
length? I will ask Europa if the list is unable to help. Thanks.
Regards
Tony Renshaw

Hi Craig,
If you shorten the link rod, don=92t you change the geometry of the tab
displacement? I know Bob Harrison did a similar thing, and he hasn=92t
had any problems with the consequence. I will have to take a closer
look, as it is an intricate mechanism, and I take my hat off to Ivan and
co for designing it. How you do that makes me envious. I might get
another link rod and experiment. Scott from Ray Allen is very helpful,
so if I stuff it up I=92m sure he will come to the rescue
Thanks for replying.
Regards
Tony Renshaw
