Well I didn't hurry but last night I tied the axle to the springs so I could put the wheels on and roll the thing around easier. I used the 34.87" from rear frame as the guide but this is way off.

BUT, here's another pic from the internet. The line marked is a plumb line marking of the original axle.

This pic is from someone who used a TCI spring and shock setup on their rear:

My driveshaft is from a Van and is a well used junkyard find and happens to be precisely correct for a T5 swap into an AD and the only way it works is if the rear axle is in the position as pictured in the last pic.
