Lol maybe the guy sent me the wrong gears instead. Idk

If so it is no big deal as long as the front and rear are matched.
You can make up for it with gearing on the pinion and spur.

Best thing to do would be to pop open the front and rear diffs to confirm tooth count before doing anything else.

Then you might have mismatched diffs and that would greatly rob power too.
