build a gmaxx and i need help

[Rivermaxx]

So now you are going to have to buy 2 hard to (get & find) custom made bones instead of one.You need +10mm bone in addition to what?? IMHO I would use a standard ue 57.5mm titanium bone the front and figure out the back after mock up. If this helps I have these bones availiable. UE titanium 57.5 , 70mm and 100.5mm. I also have rcalloys stainless 57mm and 95mm. I have steel 70mm,94mm,110mm and 142mm.
