You are running a modified/cut down? Dana back there. What is your pinion angle on that Dana? Where the perched welded on with the right pinion angle.

You have aftermarket rear shackles. Are they stock height?

You are running a T56 trans with a homemade trans mount. The engine and trans may be angled up or down from stock position

You have a solid motor mount. The engine and trans may be angled up or down from stock position

I had measured the pinion angle a while ago, in the initial T56 swap, but dont recall what it is...but we did order the diff from Strange, it is stock a-body width, perches are welded at stock width as well..so it should presumably be at stock pinion angle.

Shackles were what the car had when we bought it, never thought anything of them...comparing pics now it looks like the shackles may be 1" shorter

I had measured engine/trans angle before and after the T56 swap, i made sure it remained the same (this was also when i put the solid motor mount in).

Thanks everyone for the thoughts and comments!
