Stuck 3rd member .. any ideas?

[chillware]

So I'm tearing down my rear end for a rebuild and I can't get the 3rd member out..

It's a 12 bolt out of my '66 C10. I've got the main caps off, I pulled the large pin out that goes through the spider gears. That literally took me an hour of hammering to get out because it was worn/swelled/locked/rusted in there.

The axles are also out..

I just can't get the third member to budge.. do i just need to get a bigger pry bar and some more muscle behind it?

I can tell that moisture has been in there before, there is a good amount of pitting on the teeth of the ring gear.

Am I missing something else that's holding it in? I don't see any thing else that could be other that it could be rusted in to place..

Thanks for your help!
