I do, but I'm a little worried about the sparks it will create, I have a pretty gnarly oil leak in that area.

It sounds like cutting it off is about the only option left. The bolt is probably already jacked up, so it will need to be replaced anyway. Cut the bolt off, get the prop shaft out of the way, then you'll have to remove the output flange in order to replace the bolt. Might as well replace all eight (both shaft ends) while you're at it.
I did mine yesterday.

I would use one of these Résultats Google Recherche d'images correspondant à http://www.toolstop.co.uk/components/com_virtuemart/shop_image/product/e2be4c39fc7f53beb0d74d565acaa9ad.jpg and don't concern yourself about the bolt it's probably shot already. You'll need to take off the drive flange (tough job) but then replace all the nuts and bolts both ends of the propshaft. Make sure you torque up the diff flange nut correctly and use a new nut. Also check the pre-load on the diff flange after you've torqued the nut back on. If you're worried about the oil around spray the area with water first and have a CO2 or powder fire extinguisher handy.

Finally! Got the nut off!
heh heh.
But yeah, got it off, but now I have another problem... All the nuts are off, but the driveshaft seems stuck, I cant get it off for the life of me. I've tried wedging a screwdriver in there, hitting it with a hammer, nothing. Any advice on that?

OK have a go at this.
Use a non-metric wrench that almost fits.
Get a wrench and a hammer and whack the wrench until it expands a bit and fits the nut.
Then whack the wrench counter clock wise.
Or if you are up on a lift - put a small pipe on it - the end of a jack pipe from the floor jack works fine.

You may want to sacrifice a wrench by cutting it in two to get an area to hit with say a 4 pound mallet.

Assuming 13mm nuts. You may be able to whack a 1/2" wrench on it.
13 mm is 0.0511811

1/2 is .5

So .011811 is the difference.

May be enough to make it really fit well.
Or better yet - try to whack a 1/2" socket onto the nut. A 12 point would probably go on.

The 1/2 inch difference is .02mm. Bet that will work.

You could try a black hardened impact wrench socket - whack a 1/2 of one of those onto the bolt.
You can get impact sockets at the local autoparts store as they are made in China and are basically disposable.

When you re-assemble the flanges put a very light smear of copper grease Résultats Google Recherche d'images correspondant à http://www.redrc.net/wp-content/uploads/2009/04/ultimatecoppergrease.jpg on the flange faces and it'll come apart easier next time. I always use this stuff on all flange faces, disk brakes, wheels onto wheel hubs etc. saves a lot of fighting then later on.

Good to know!
Ordered a new shaft for 250$, going to put it on on Thursday.
Any advice or things I need to know when putting it on?

Where'd you get a shaft for $250?
