If what I've found is correct, one wheel needs 10 19/32" spokes and the other needs 10 5/8" spokes.
10 19/32" is shorter than 10 5/8" by 1/32" (or .79mm.) Unless you have access to older NOS spokes, you're going to be buying your spokes in mm. 10 19/32 is 269.08125 mm, 10 5/8" is 269.875 mm. Most spokes that I've found recently have all been advertised as 269 mm. IF they're exactly 269 mm, then they're actually a little on the short side for either length needed, but that will be taken up inside the nipple. I guess you could file off that 1/32" off the 10 5/8" to get a 10 19/32" spoke is it really matters that much - if it's really a 10 5/8" spoke that you're getting in the first place. But by not having any spoke extend beyond the nipple lessens the chance of rupturing the rim strip and it also allows a screw driver to fit snugly into the groove in the nipple. So if you buy 72 of the 269mm spokes, you'll be able to do both the front and rear wheels.
