6.1 Hemi 69 Barracuda Fastback Father Son Project

Working on getting the correct dimensions for a Dr. Diff Custom 8-3/4 Housing and axles for the fish.
Set the old leaf springs up with the Dr. Diff .5" offset hangers and set the 17x9 year one wheels in the wheel wells where I thought they would look good. Not having a housing that has the perches in the right location, I just set the B-Body housing that came with the car in there to get the wheels eyeballed.
With the car resting on the old leaf springs and the springs resting on jack stands I got the center of the axle housing just a touch lower than the center hole of the wheels. Figure that it will sit a little lower than an empty shell...
Moved the tires around until I got them where they have clearance from the springs on the inside and from the wheel opening inner lips on the outside.
Measures 56.5" from back of wheel to back of wheel.
Going to give Cass the measurements, my Cherokee Rear Disc Brake setup and have him build me an 8-3/4 to fit.
Here is a couple views of the mock-up...

Looking up at the clearance from the wheel opening lip.
