I was thinking...(which is dangerous)

If you were to SAS an X what would be the easiest axle...

I thought that a Toyota 8" SFA would fit well, and with six-lug would allow usage of current wheels.

I know Ian used to have such a beast (SFA 4-Runner), so if he or anyone can help shed some light on the subject, let me know. Here's my questions:

How similar is the track width?
Is the diff on the correct side (I think it is?)
Are the steering knuckles set up to take current Xterra steering geometry?
Stock toy suspension height-vs-Xterra, would stock springs be about the same as stock X?
