I did check the backspacing at 6 inches. Also 9 inch width. The Dana 30 should be 60.5. So, add 3 twice, 66.5. Then minus 9, 57.5. I come up with 1460.5. So 10mm to spare, or no room for spacers. The Ford 8.8 is 58.5 width. So, 1409.7, 60.3 to spare or 2.375. Not much to get a spacer/adapter in there. Could check around though. Also, check any rules for spacers. Some States in the US do not allow them. As before I am planning to use Yukon Axles. It has a 5on5 option bolt circle. I have a plan to upgrade the rear to WJ brakes.
