CRT.5 Aluminum Hex Hubs?

[BP-Revo]

Hey, I remember reading somewhere that Traxxas 12mm Hex's do not work on the CRT.5.

Anyway, I am in need of some aluminum hex hubs for my CRT .5 and was wondering if there were any more common ones I can use. The only place I found that sells actual OFNA CRT .5 Aluminum Hexes is Impakt RC. And I don't feel like paying 8 dollars shipping for 11 dollar hex hubs.
