How hard is it to do a gear swap?
it should not be that difficult, just don't cut any corners when it comes to the measuring and having the right tools. other than that just read up on it, all I could reccomend is do not cut corners on tools
I would recemmend taking it to a rear end shop of some sort to do it. Gears are touchy. My friends dad has been doing gears for 25 years. He says you have to be very precise and know what you're doing. Or, if you have a friend that maybe has some experience on rear ends, have him help you. If you don't get things set up just perfectly your gears will whine and you could shim the gears. Just be careful.

For some reason the 8.8's are always easy. But when I did my camaro rear it was the worst ever it just would not set up right. Took me about 12 hours on and off.
What you're going to find most difficult is judging whether or not the contact pattern is correct. Sometimes it's perfect on one side and no where close on the other (drive vs coast sides). Then you have to figure out what to change to make it right.
Be sure you write everything down as far as shim size, locations, notes on what the pattern looked like with that shim set up, etc. The judgement part is the most difficult, nothing you read will teach you that.
