Default AP1 vs AP2 Differential unit

Just curious if anyone knows if there's any difference between AP1 and AP2 OEM differential units... are they interchangeable? Did any other change occur in the design of the diff from model year to model year within AP1?

Thanks a lot for your knowledge.

-the drive flange is different. you can swap them from dif to dif to fit in either car.

The pinion oiling is supposedly improved, and it might be a little beefier.

I'm pretty sure all AP1's are the same.
