Ground Adjustable Rudder Pedals

I have to say I'm a bit disappointed in the ground adjustable rudder pedal kit so far. First, the F-8108 attach angles are supposed to have a joggle in them at each end but it's really just a slight bend in the flange of the angle that doesn't do anything.

Second, the weld on the rudder axel tab interferes with it lying flat against the F-8108 attached angle leaving a 1/16" gap also making it impossible to get the 15 1/4" dimension from side to side they call for.

I reached out to Vans about the weld interference and they said it's allowable to relieve the cutout in the angle to accommodate the weld but that means repeating that process 8x for the 8 cutouts. I thought about adding a washer to give me clearance for the weld but that will make it impossible to achieve the 15 1/4" spacing called out. I'm not sure how critical the spacing is. My fuselage is upside down right now so I'm working on other small projects.

Has anyone else run into these problems? And if so, how did you solve them. I'm at the point of almost ordering the inflight adjustable rudder pedals but don't want to turn this thread into a debate between the two. I already read all of those. :)

Biggest regret

My weldments from 2019 actually fit the rails well. I had a terrible time getting my rails to fit for slightly different reasons. Changing pilot sizes is terrible.
If I had known I would have put the flight adjustable in.
 
I had the same problem with the F-8108 rails. Considered using shims to make up the difference, but decided some forceful persuasion was better. Basically set it up between blocks of wood and beat it with a hammer. If it's good enough for the main longerons, it's good enough for these rails.

At the end of it all the rails turned out very well and fit nicely.

Thanks David. Great idea. I think I'll try it as well.
