I spoke with a guy at
http://www.raxles.com/ he does not have any parts so he can not rebuild the stock axles but after talking with him he said he can get newer STI axle parts.
I told him I think there is some interchangeability with the svx but I was not sure exactly how much.
Do any of you know if he could build svx axles using a stock axle and sti joints?
