I watched the above video, which I found in a similar thread from January. I guess having this problem in mid-October is kinda funny...
I did end up just buying the #8 hardware since I couldn't find the DeWalt (turns out it's at a mentor's house). We'll keep all of this in mind though, for future mating of wheels, sprockets, and spacers.
Thanks everyone!
