for everybody that is using offset shackles

I am always wondering why the tire clearance issue comes up when people do spring relocations.
The correct answer:
These cars had +/- 1/8" tolerance in the sheet metal assembly on the assembly line. So not everyone will have the same answer. And what fit on ones persons car may not fit someone else's. But it also depends on if your tires are closer to the spring in the front or the back. So measure your car.

I would agree with Bob McCarty on this, as I've measured low millage untouched or wrecked cars. While you can move the front perch in 1/2". Depending how your spring sets itself in the rear hangers will dictate how much clearance you have for your tire. A 1/2" front perch relocation & 3/4" offset shackle could give you 3/4" more tire clearance.
