Is 1/2" leaf spring relocation worth the trouble?

If you are putting the B rear under the car WITHOUT relocating the perches then I would say it would be best to relocate the spring mounts to match the rear perch width.

If you are worried about the extra width of the B axel, wheels with a different Backspace can solve that.

If you have specific wheels and they need an additional inward spacing of the spring to fit, then you have to move the spring or space the wheel out if you can

I definitely am moving the perches, and probably know the way I'm going, but just wanted some validation on my ideas. I'll probably never get this far, but my 70 with the 8.75s is close as the front suspension is already sorted with all BAC type upgrades. The cars pictured below both have 18×10 outback
