Angry D110 Front Suspension Install

OK, basically I'm getting pissed because I know this must be something much more simple than I can realize at this moment. I am rebuilding a 1983 D110 (see Registry), and have finally made some progress in the past couple months after 3 years.

After getting the original front axle lined up, Terra Firma shock turrets installed, mounted the front springs and shocks, and reinstalling the original trailing arms, the shocks/shock towers appear to be "twisting" in their mounts (see pics). When some NAS shorter trailing arms are used, it appears to rectify the issue somewhat, which tells me that either:

1) the axle is "turned"/canted down/up too much, which have affected the spring mounts on the axle, OR
2) the axle is aligned incorrectly from left to right, OR
3) the hell if I know

Any thoughts? Other than some smaller issues, it's about the only issue I have left on my rebuild to get completed.

couple questions

1. what is angle of lower spring perches
2. stand height towers?
3. pinion angle?

Looks to me that you need to start measuring angles and lengths. I am going to guess either too much lift or radius arm length is off. You likely need cranked radius arms or a different length arm. Basically the lower perch where the shock mounts is at an angle and or further forward or back from stock.

What spring lift did you use? Did you set the toe to the stock bar length?

Are you running a lift? Is the Engine in?

If the engine & transmission isn't in then the springs will push the chassis up very high, the tie bar from the chassis to the axle will be running at a much steeper angle than intended and will pull the axle over as a consequence.
Drop the engine in and my bet is it'll sort itself out for you.

I think those are in backwards. I had a set and remember they were NOT universal.
