Wing Spar Center Section Fit
Not at this stage yet, but when I built, I machined some hard Delrin spacers for the spar carrythrough before I riveted it to the fuselage structure. In my opinion Vans instructions are poor here (I think they mention a wood block). The spacing should have a machined spacer and I think Vans should supply it.
However, this doesn't help you. This also happened to a friend of mine, and Vans recommended de-riveting the skin overlap on the bottom of the fuselage, insert the spars (or machined spacers would probably work)and re-rivet the skin overlap.
