Are all front SVX spindles the same?

[fateo66]

Hi just bought a SVX to swap the drive train into my WRX and I have quickly relised that there is several issues. The first and only on the front is the ball joint size. My donor car is a 92 and i was wondering if all svx's have small ball joints or are the later ones like the rest of subarus' with large ball joints? I came across one thread where a guy had made a reference to two different hub sizes but I wasn't sure if what he was referring to was what i am looking for.
