Earlier tanks are referred to as pre punch. The later tanks are referred to as matched hole. On the earlier kits only the skins. And spars and the back baffle had pre punched rivet holes in them. The ribs did not have rivet holes pre-punched on them. On the later matched hole Kits all the parts have undersized rivet holes already punched from the factory.
You may be able to use the later. Kit parts. I would suggest calling Vans and discussing this with them. to get an authoritative answer.
