Relocating the rear differential 1.25” towards the rear of the vehicle on a 72 Dart

Ive heard of spacing the front hangers back, but usually only 1/4-1/2".
I used the super stock spring hangers when I changed to ss springs, and drilled the hanger where I wanted. The rear moved back an inch.
I certainly never noticed any loss of traction. Best of 1.59 60 ft.
Rear is centered better, and I have room for a 30" tire.
