"1970 Pro Touring Dart Build"

The carriage bolts won't work, It will still hit.

Options-
A: I cut out the spring boxes and put new ones in but moved for sway bar clearance.
B: Say to hell with the anti sway bar, move the axle back 1.5" to were i had it.

I could go either way. If you were in my shoes what would you do?
