So I took apart the wheels and measured the spokes.

36 308mm spokes on the front.
18 308mm spokes on the rear NDS.
17 306mm spokes on the rear DS, and
1 303 mm spoke on the rear DS (how did THAT get in there?)

Still trying to find one source that will sell me a combo of 2/1.65/2mm for the front and NDS, and 2/1.8/2mm for the rear, in the correct size.

I'll be reaching out to DansComp and Yohimbo on Monday to see if they can get the spokes (Sapim Race and D-Light, or DT Swiss Competition and Competition Race) I want.
