You may have to parts bin engineer this, with CF outer joints. I used an aftermarket brand of axles, by buying 2x CF axles, and 2x of Charger/Challenger/LX axles, and shopped by specification to get the length I thought I'd need, and then disassembled, swapped parts around until I got what I needed. Tedious, but it worked. I cannot stress enough, use the same brand, as they will tend to stick to common items that can be swapped between joints.
