Broken Bolt on Woodman Lefty Hub

I recently reminded myself why I need to buy a torque wrench.... I over torqued the self-extracting bolt on my lefty hub and it snapped.

Does anyone know or if I can get a replacement hub bolt? I have the Woodman Lefty XL hub. Seems logical that I can...but I haven't seen this in the forums before...

Also, do I need any special tools or have to replace any seals when I change out this bolt. I don't see exactly how this bolt comes out the of end cap....

The bearings should still be good, but maybe this is a good time to replace them...hmmmm
