RV-10 Wing dimension question

I'm building a wing stand for QB wings. I may add extra cross braces to the design I round (On Rodrigo's build log), so I want to be sure of clearances.

Can Anyone tell me the distance from the leading edge of the spar to the wing leading edge?

Thanks in advance.

Right at 16" from the leading edge of the wing to the front face of the wing spar.

I get ~18? measuring the outboard rib from the flange and allowing for the skin. Tank ribs are closer to 16? but they don?t touch the spar.

Thanks - just what I was looking for!
