RV7 wing attachment question

A close relative is building an RV7 and is ready to attach the wings for the
first time. The alignment of the holes in the center spar section front and
back is off enough that a hardware store bolt will not pass through both
sides. I estimate the alignment is off by 1/32 to 3/64 inch perhaps more on
the port side. I am not an aeronautical engineer nor have I built a plane
but to me this is excessive and would tend to stress the close tolerance
bolts and spars as the bolts are forcibly driven in.

He says his 'mentor', who has built two planes, says all is OK (though the
'mentor' has not personally inspected the plane).
Am I being paranoid? My concern is for his life....
