The correction should be something like that. You have to remove some of the plastic from the leading edge under the part to move it forward. Personally I would cut out the barrels and made them separate. In the way the fitting of the parts to the holes in the wing would be fine without any correction to the spacing.

I'm sure you'll make it work Ralph.
The resin parts can be made straight with quite warm water. Secondly the Eduard may be the final firm offered the resin parts. But the set could be made by their co-manufacturer.
BTW I edited my post above and attached a shot with the second solution.
