Hi Bob,
I don't have that kit, but I can't imagine it not being for the spar after cut to length. I know that sometimes, for cost savings, etc. different length wood is shipped with the kits. Or if nothing else, they aren't always cut to any sort of exact length tolerances.
Let us know how it goes, it's been a while since I've seen that kit built.. sounds like a good build thread.
