I see where the miscommunication came from. Those are the 996 narrowbody hollow spokes, equal to the 993 turbo hollow spokes. But, they are NOT the 996 turbo hollow spokes.

Here are the part numbers for the 996 turbo hollow spokes:
Front: 996.362.136.04
Rear: 996.362.142.11

They are also of different dimensions. The front 996 turbo is 8x18 with a 50 mm offset, while the 993 turbo/996 narrowbody is 8x18 with a 52 mm offset . Small difference, really, but the rear difference is more substantial. The rear 996 turbo is 11X18 with a 45 mm offset, while the 993 turbo is 10x18 with a 65mm offset. I'm quoting your numbers for the latter, as I only know the 996 turbo numbers.

Those are also the exact dimensions for the 996 C4S solids. AW 21 has the C4S, and the easiest swap would be to get the exact same wheels but hollow spokes from a 996 turbo, not the 993 turbo. Those are what I have, and I just swap street tires/wheels on the solids with track tires/wheels on the hollows whenever the need arises.
