Corn flakes on gearbox fluid. Center diff bad.

Hi guys. I recently bought a used tranny comming from a totalled '95 gsx and I was going to use it on my '91 Talon. Once i had it installed I tried to replace the gearbox fluid and surprise!! some pieces of metal came out.

I was suspecting the center diff and I was right:

As you can see one of the washers is broken and the other one just dissapeared.

So I have few questions.
1- Is the '91 center diff compatible with that '95 gearbox? Can I just swap diffs?

2- Do I have to disassemble the whole gearbox to clean all the metal particles that could remain there right?

3- If i want to repair the bad diff, how do I know the right washer thickness I should use? I read the manual and It's pretty confusing, I don't get what it says.

Hope you guys can give me some advice.

How do you plan on using a 2g tranny in your 1g car? The mounts are different.

just reusing the 1G mounts.
The 2G tranny is already mounted on the car.
But i foundout the diff was bad after the installation.
