Control Column, Stick and F-449 bracket

Forgive me for asking RV4 builders for help yet again, but once more I have a query. I am installing the control column under the seat and the 'ears' for the aileron push rods have ended up about 3/8" too far aft. You can see a better description here

I would be interested to know:
a) is this a common problem?
b) what approach have people used to solve it?
c) assuming the answer results in moving the stick forward does this present any issues?

Thanks!

PS It has occured to me that perhaps they are not meant to be centrally located and the aileron pushrods sweep forward? If so they are going to be tight against the passenger footwells.
 
F-449

Thanks for the replies. For the record this is what VANS had to say:

" I've heard that in some cases the ears seem to be too far back like
this, I don't know why; maybe the plans, maybe the parts. It's usually
not necessary to do anything. The fore and aft movement of the
pushrods is negligible at the fuse side, and it doesn't matter if they
are centered in the hole or not, so long as they have decent
clearance (say 3/16" min). If they don't, the hole can be enlarged a
little.

You can leave the weldment mounted the 7/16 further forward, I
doubt it will affect much. The stick won't hit the panel if you move it
forward, it goes under it. It's possible the rear stick will hit the front
seat back though; you may need to increase the curvature to clear.
"
 
Did anyone have an issue when moving the control column 3/8" forward. I am having the same issues as previously described. It appears the "ears" that were welded on for the aileron push rods are back a bit farther than indicated in the plans.
