| − | === | + | ====ID==== |
| + | An easy way to tell the difference between the 8-inch and the 9-inch Ford differential is that on an 8-inch, a socket will fit on the lower nuts seen in this picture. Since the pinion centerline is lower on a 9-inch, a wrench is needed to gain clearance. | ||

| + | |||
| + | The corporate 10 bolt 8.5 inch rear end uses a 2-series for 2.41 and 2.56 ratios and a 3-series carrier for 2.73 and lower (higher numerically) ratios. | ||
| + | |||
| + | |||
| + | ====10 bolt ID==== | ||
| + | If you don't have the codes on hand to identify if a 10 bolt rear end is an 8.5" or not, you can measure the distance between the very bottom bolt for the cover and the next adjacent bolt (either right of left), it will be 3-3/4" for a 8.5" and 3-1/4" for a 7.5". | ||
| + | |||
| + | The ring gear of the corporate 10 bolt is secured by 7/16" '''LH''' bolts- 10 of them. The ring gear is (as mentioned) 8.5" diameter and the pinion shaft diameter is the same as the 12 bolt at 1.625". | ||
