Yeah, wing ribs are about the easiest thing, I can either enter the original tip and root rib into my cad program and loft the rest. Or, I can just use some of the ribs I already have and design my own wing. If there is a full side view and wing and tail, I'm pretty happy. The fuselage formers would be a bonus. The .40 size P-51 has everything but the ribs, but it does have a tip and a root, so it is no problem to scratch them. I'll also have the complete kit, if I buy it, so I can trace what's missing on the back of the plans. I just hate it when you get no full size plans, a LOT of the older kits come this way.
