WTB (or learn good source for): 'hidden' 5th bolt for Campagnolo 10 spd crank

Sometime in last year I lost the hidden 5th chainring bolt for a 10 spd alloy Recond crank, the one that goes into the back of the crank arm. Can anyone recommend a good source for a replacement?

KCNC Campagnolo chainring bolt kits are ~$20 on eBay if you don’t want to go the OEM route

I think those work with the 11 spd 5-arm cranks, but NOT earlier alloy 9/10 5-arm cranks. But I'd be glad to be corrected if somebody knows those KCNC bolts will work.

Cycle365 on ebay has an absurd number of genuine Campy spares. Perhaps there?
