Crawling over something
You will be fine!! Torque multiplication is you friend.
You are still running a 4l60, correct? If so it's plenty.

Build what you want unless you're planning on giving it to me then build what you want and I'll deal with it 
With an auto, you'll likely be fine! You can always put different gears in the atlas down the road.

Anyone run an atlas with an IPOR belly skid?
I'm curious as to how flat I'm able to mount it with my current setup.

Oh, gratuitous pic of the giant hunk of aluminum.

very nice

I twisted the previous truss so decided I may as well replace it while I'm doing the transfer case.
Picked up one of Artec's modular trusses (4 wheel parts 25% off coupon!). It looks good and is gusseted enough that I don't think I'll have to do this again.

Rear truss is burned in and the truck is back on its tires. Should be ready to wheel by the end of next week with some luck.

I got the 32 spline input out of the Atlas, but had to order in input seal for the smaller diameter 27 spline shaft. AA were awesome over the phone (they have fantastic customer service) in that they gave me an applicable part number for the seal even though they've now gone to a non-interchange seal made specifically for the atlas.
Mock-up for the transfer case will be tomorrow, and I'll measure and weld up the driveshafts over the weekend (I'll have to wait until next week sometime to balance them on a lathe).

I had to come up with a really odd-ball seal (because I didn't have a lathe) for my aw5/dana 300 transfer case adapter. https://www.timken.com/resources/
is your friend, they list the seals by size, but have a really good search function that allows you to spec out your seal. A quick google of the part number nets you the seal.
the problem I had was the OD of the area being sealed and the ID (shaft diameter) gave me about 1/4" difference with which to put a pressure seal (meaning it could hold pressure)....

I didn't think to look at timken (and never knew they had a search function on their site). Thanks for the info!

Atlas is in without much trouble. I need to move my fuel lines and pump up an inch or two for clearance (no trouble at all), and then get the belly pan on to check for clearances.

I just realized that there isn't many days left until I'd planned to go wheeling (4th of July week). Time to get some stuff done.

Case is installed! Tomorrow I'll get the rear transfer case mount finished, install the shifters (they landed in a great spot!), and start the drivelines (maybe even finish them, minus balancing).

Wrapped up just about everything today, but when I went to measure for the rear driveline, I realized I hadn't yet installed the rear CV flange. Then I realized I'd forgotten to order it.... 
Well, I ordered the flange that should be here monday.
Rear driveline is going to be.....
~25" !!!

With the exception of a few small things, the 40 is again road/trail ready. Rear driveshaft ended up at 25.75", a huge improvement over what it was.
I have to pull the hoses for the heater, as the heater core is leaking, and put some spacers in for the upper heims in the rear. Other than that though, the truck is good to go.

Had a pretty awesome day wheeling.
Everyone we know was either working, on their way to a crawl competition, or out of town, so the Mrs and I went out for a solo venture.
I ended up not attempting Can Opener as you typically have to climb really high on the driver's side wall to get up on the rocks, and a flop while solo just isn't a good idea.
The truck ran great, with no issues, and the Atlas proved plenty deep for the rocks (and not so deep that some whoopow couldn't be had for a bump).
I'm going to look at maybe adding a couple of fans under the hood vents to pull some heat from under hood. Temps never got above 220 on really heavy, long climbs, but I'd like to evacuate some more of the heat if possible.
