Suggestion: call Brodak's and ask them.
John Parker should be able to help.
I did have a conversation with John. John cuts my laser files and he makes great custom tanks. He made the tank for the Mig-3 from my balsa tank mock-up. Perfect! Not a 1/32 off! I mentioned his work in the Mig-3 build over at CFC Graphics vendor's corner.
He said the Smoothie ARF was produced in China and he would have no way of knowing if the ribs are identical.
Checking an ARF is pointless because they are covered with some iron on material?
John did say he would try to find and look for a Smoothie wing that wasn't covered and get back to me.
John is a great guy, be interesting to know the scoop on the rib kit and the ARF rib.
I believe there was some conversation about the Smoothie airfoil being improved and it not being that of the original Smoothie? Not sure though.
