I have the Arch-Warrior STC on my plane (purchased that way) and the prop was changed as part of the STC. One thing to note is that the gap between the spinner and the cowling is larger than normal, I'm assuming because the STC specified the prop spacer length, which in turn I am assuming is based off the cherokee 180 cowling dimensions or archer dimensions.
Looking back through the paperwork though I see that it doesn't seem to specify a spacer length, only a prop model. Have any of you other Arch-Warrior owners looked at this? Better yet, what prop do you have on there now? Mine is the 76em8s5-0-60.
