wider rear axle

[Mountain Yoat]

Dutchman made me a set of inners for a custom front axle. Can't get them dual heat treated unless BIG $$$ in pocket.
Does anyone know if Superior Axle makes  custom lengths in the New 300M (Longfields+Inners)? Sure would like a set of those

I am thinking of doing an offset 3rd member in a rear axle for a project I might be building. Basically I want to spin the front axle around, cut the steer knuckles off, weld on rear brake backing plate flanges, and use it for an offset rear axle. To do this I need custom length rear axle shafts.

Does anyone know who can make them?
