Rear Shock Absorber Length - Cougar vs Mustang

Thanks Bill,
My suspension geometry is likely less like the original than I thought. The KYB shocks show a compressed length of 11.3". That would have it bottom out on the shocks well before the axle hits the bump stops. I’m running the WCCC 43460 leaf springs. They are advertised as competition springs, stiffer and 1/2 - 1" lower. After running them for a couple of years I’m convinced that they were a full inch or more lower. I also tend to keep the trunk full of tools. That and the 235-60R14 tires (another 3/4" lower) had me dragging the mufflers too often. Now running a 5" shackle (vs 3-1/2" - that compensates for the tire size) and it looks to still be lower than factory. At this point it’s back together with the Scott Drake shocks and I’m inclined to leave it that way. This looks like it should be good and I don’t see any better options. Again, any other thoughts?
Hopefully the discussion and learnings here may help others.
