[EA82 rear axle shaft differences from 86 to newer?]

I have an 89 GL Wagon 3.9 gear ratio on my rear end and I'm wondering if it's safe to switch it out to a 1990 rear end same ratio I hope or different.  Not to many parts around for this car....or does anyone know where to go for after market or rebuilt subaru rear ends?  Thanks, A <3

Hi all and thanks for allowing me to join your group.

 

I am a 40 y/o single mom, and I come from a long line of mechanics...so I like to fix my own car and fix up my own car.

 

I'm just here to learn and ask questions.  Good help from knowledgable sources is invaluable.

 

Thanks for welcoming me in advance.
