I thought you modded the rear output using the slip yoke. I see now that you just unbolted the slip yoke from your DS and left it in the tcase. lol Indeed I've looked at those options, yet it just seemed to always get put off. Instead, I just recently spied and good deal on a RockTrac Tcase.
Got it last week and very excited. Now it's DS thing to work out and a CAD thing since the 1 ton axles are far from ready. Before this deal came along, I had my option down to an Atlas and the ORD Magnum+np205. I still have an option to double up down the road.
For your new rear springs are you considering moving the front hangers for them? Buddy of mine did when he put chevy 63" in. That included RuffStuff Reverse Shackle Flip on the rear, 6" shackles. He did have to use the factory block.
Unclear about the Atlas issues.
I use photobucket.com. I'm sure iPhone has an app for it.
1. Take picture with phone
2. Upload to your photobucket account. Organize into various albums and privacy settings.
3. For each image a URL is generated. Copy that and post here. Over time you'll figure out various other options. This process will be similar to imageshack, flickr, picasa, etc.
