If the side ducts fit well on stock body, as do df side ducts, then its safe safe to say df side ducts should not take much adjusting
if any to fit kite skirts?
... not sure what you're asking here. how would DF ducts would have bearing on fitment kite side skirts? I can say, kite ducts seemed about 90% as well as my DF side skirts - the DF stuff I've ordered has 100% dead on fitment (although it's all been recent stuff not early production runs). Kite, note quite as good but still very good.
