Success! Here's what it took.
1. I started the belt high up on the crank, at about 8-9 o'clock. Used a C-clamp to hold it in place.
2. Routed it past the the oil pump and up to the 5-8 cam sprocket. This is where a tiny bit of slack forms. Remembering a tip Mark Robinson (thanks Mark!) told me, I used a 17 mm socket and turned the sprocket 1 tooth CW past the mark. Once I got the belt on the sprocket, I then used the wrench to turn it CCW back to normal, which took up that tiny bit of slack. I clamped the belt to the sprocket.
3. Routed the belt under the water pump and up to the 1-4 cam sprocket. I had to use the wrench to turn this CW about 8 teeth because when I pulled the old belt off, this is the one that "fell." Just like I did on the driver's cam, I rotated the passenger sprocket 1 tooth CW past the mark so I could rotate it back once I got the belt on in order to pull the belt super tight. Put a clamp on it.
4. Routed it over the Pknsr pulley. It took some wiggling to get it on, but it when on after 30 seconds or so of messing with it.

Thanks for your help everyone.
