Vertical stab ribs

[TTAero]

Can anyone tell me what their top airfoil shaped rib measures please? Also a photo of that area of the assembly would be helpful because I would like to verify some other things.I bought these ribs from Mark and installing them on a VR3 kit. I scale the plans and it should be about 19 inches. This one is 17.5 long. The other 2 fit well so I’m stumped. I also dug through the other ribs for the horizontal to make sure nothing was mixed up in the bundles but no luck. Thank you!

My 4 place top rib doesn’t have an airfoil shape. I’m assuming the Patrol does?

4 place is more of a difference than I thought. Patrol has 3 airfoil ribs and a flat top rib like yours.
