Am I trouble here? Gears turned inside diff housing

[ColinOpseth]

Hey guys,
I know this isn't a truck question, but since I have a '70 CST big block shortbed I figure I'm allowed to post.

I am working on my '72 Vega. It has a 12 bolt with 3.31 posi in it. The axles are c-clip eliminator axles with no c-clips but 9" ends on it. I removed the axles to change the stock length wheel studs for longer ones.

In that process, it appears I may have turned the differential and one of the thrust washers fell out (the ones held in by the cross shaft bolt). At that time, one of the spider gears (or whatever they're called) turned and I can't get the cross shaft back in. Do I have to pull the whole unit now to fix this? They are seriously wedged in there but the rear end isn't binding at all.

Any help is appreciated. I'd like to get the Vega out and cruise. It's a beautiful day today!

Thanks,
Colin
