Welcome to the forum.
If you are going to flip the axles, I recommend you do a wet bolt kit as well. One of the weakest links in the suspension, the plastic bushings wear out fairly quickly, then the bolts and shackles start to wear.
Here's a link to an axle flip kit.
Lots of good resources for parts online, unfortunately the shipping kills us, unless you can get stuff shipped to a US address and pick it up. I'm only an hour from the border, so I can pick parts up and import them myself. Last two trips I've saved about $3K even with our weak dollar. Many of the online stores have free shipping offers the US addresses.
