1973 Plymouth Duster repair and rebuild

No you don't understand. For the third time. The angle in reference to the perches is 5 degrees nose down.
Your right, I dont understand. I am so confused and I am at the point of giving up until I can get a job and pay someone to do this.

And if the barracuda axle geometry is different than the duster axle geometry, then I really screwed up. As my new 8.8 is welded up like the barracuda axle.
