Gmaxx help

[Kigne]

Hi all,
First of all, let me say that this forum is more than an inspiration!
Recently, and finally, I bought the slipperential.
After some brainstorming and some hours on this forum, I found my way to mount on my Gmaxx.
But now I have a problem... the dogbones!!!
I had tried to contact rcalloys.com but they are no longer in business.
Can someone help me find a place to order them or a way to homemade something that can work?
The front dogbones is around 30mm and the rear one is more or less 173mm.

P.S. Sorry for my very school english
Thanks
