I know this is a late response, but Feb/March is when NASCAR is gearing up. When Sunday is your day off for the week....
I got my ‘07 in ‘10, and MrsSgtBob’s ‘07 in ‘11 (she threatened to commandeer mine). And both are equipped with Dana 44s front, and rear. I think we got a deal at 21k each. I didn’t know at the time that those were only standard on the Rubicon model. We have the Sahara.
You guys surely did.

The Dana 44 is about $2,700 new, uninstalled.
And used, they are very hard to fine in good, unfouled up condition.
The axel is an incredible piece of engineering. You should be proud to own 2 of them.
