Need wheel hex 12mm nut for Arrma Granite Mega 2wd

[Doooford]

Morning everyone, last year I picked up a Arrma Granite Mega 2wd for a bit of lockdown fun,
Not long after a wheel pingeed off and the hex nut was nowhere to be found.
I've been ordering replacements but none seem to go all the way over the pin. The latest pair I got was 12mm cast alloy 12mm hexes, that look perfect but don't slide all the way down. Part number for metal was AR330132.
Does anyone know where to source a nut that will fit, nylon or alloy?
Many thanks.

Have you ordered a factory replacement?

Ooops, nice catch. I glossed over the 2WD part.

But it looks like the nuts are in stock at Horizon: https://www.horizonhobby.com/product/serrated-flange-wheel-nut-4mm-4/ARAC9750.html
