6-40 extended nut source

[junkman]

Bought a box lot of rc10 junk, one has a truck conversion kit. I'm pretty sure the kit would have originally had wheels that slid right on the stock rc10 axle stub. There is a whole set of matching chrome wheels and rc10 to tamiya blackfoot style adapters, but the extended nuts aren't in there. Does anyone know a place to get the nuts, or is there something else they might be called to look up on the online fastener stores? Thanks ahead.

junkman,
PM me, I was just cleaning out and sorting my junk fastener bin and found a pair of them.
