Some good news from Russia for those, who want to get R180 on their B13 legacy but for some reason can't get Spec B axles.
We successfully installed R180 on 03' JDM legacy GT(B13 started from 2003 in japan), using pre-5*114 axles from 03' JDM GDB STI(30 splines on both ends of the inner shaft, AFAIK it's the same as US pre-5*114). We used outer CV joints from (you must get mentally ready) hyundai elantra. P/N MEYLE 37-14 498 0000. One car is running them with IHI VF42 for at least 50000 kms without faults, other just got them on.
Splines count:
LGT hub - 25
STI inner shaft - 30.
Swap is a direct bolt-on, CV joints went in as if they were manufactured for that exact reason.
Don't know the situation with parts in US, but here it's almost impossible to get your hands on used spec B axles, and for new ones you have to wait a month and pay ~$1200.
STI axles are easy to find wherever you want, and usual price is $300 for pair. Meyle CV's are $100 for pair and can be found in any shop.
