Who's gotten theirs done and for how much? I've got a set of axles in the 9" that are 5X5.5 and I want em to be 5X5 or 5X4.75. I'd probably need the old holes plugged, new holes drilled and possibly some wheel studs. Anyone got a source/price for this? Thinking I want to get back to a single pattern and one spare tire again.
