While I was getting my gears changed to 3.42s, an Eaton posi put in and doing all the axle bearings, I wanted to upgrade to the T/A differential cover. I thought that it would be easier to modify for a differential oil cooler. Anyway, it was supposed to fit with the new Hotchkis rear sway bar. And it did. But with my lowered rear, the cover touched the gas tank shield, so no go.
