I won't argue with mclina - that's what I would do... but unless I can be shown the forward bulkhead from another angle it looks like there isn't a place for the front dowl.

As it sits, it looks like this is a trainer that was meant to have elastics holding the wing in place and there aren't any signs of a method to secure the leading edge by either a dowl into a bulkhead or a cross dowl to secure elastics.

Can we have some more photos? []
