There will be tons of room on the passenger side of the truck for exhaust if it comes to doing a two into one. I can crossover tube to the drivers side and run all the way back. Possibly.
 
Just ordered three gallons of Royal Purple Gearmax GL-4 for the NV4500, 6 quarts (5 plus 1 extra). I will also be using it in the np205. That way with a sealed system there can be no cross contamination. RP does very well in the cold temps here. I used the AMSOIL GL-4 last time and it was a little cheaper but I think it made the NV4500 whine a little more going down the road. Maybe just my hearing but it seemed a little "Thin" when I put it in there too. Anyway, 3 gallons will be plenty to fill the whole system with a gallon left over for any fills or leak repairs. I like running as many similar fluids as I can on my mountain rigs. It might seem like overkill but always having fluid is a good thing and the more that are the same the better.
 
Do you run your NV4500’s overfilled? I’ve seen conflicting info about that, 1pt, 1qt?

I do, I overfill by about a quart, always have. I've never really seen it make a difference in the drive ability but here's why I do it. All of the ruined NV4500's I have seen ruined, the vast majority were from low fluid due to a cracked tail housing. The tail housing gets flexed and cracks, dripping or draining fluid, killing the trans. To me it's cheap insurance if there is a drip or leak that I miss. If it's catastrophic failure then, there's not much you can do but if you develop a crap and it drips there is one more quart of fluid in there and hopefully I notice it in time. Never had an adverse effect because of it, so I keep doing it.
 
Damn near. Watching closely cause I may do exactly what you are in the future.. good combo for sure

I'm sort of wishing I had held out for 4.3 gears in the Superduty axles. 4.10 isn't going to be too bad with the 37's but 4.30 would have been a little better. I will be adding selectable lockers before Blazer Bash for sure and it will likely get regeared a little steeper at that point. Had I been able to hold out and find a set with 4.30 gears and the E-Locker that was factory in the Superduty trucks I would have run it as is, no question.

I didn’t realize there was a locker available oem, good to know.

Yup, factory e-locker was an option. From my research it really doesn't add any to the price of the axle at salvage yards either. I found a few on Car-part.com searches for 3-400 bucks. Same price for the regular sterling.
 
Yeah its the 2011 and newer super duty trucks that got the electric locker option I think. Not sure exactly what year they started but been seeing them in our trucks at work for the last couple years. From the factory they only work in 4 low due to the computer but with a switch on the dash that would be a good cheap way to get a selectable locker.
 
Today's goal is to lift the cab off the frame, and mock up the drivetrain. I was supposed to have help to get this done but it looks like as usual, I will be doing it myself. Good thing I have a dozer to lift everything. Hopefully I don't screw anything up. A 20t machine is anything but Fine control wise.
 
Well it decided to rain on and off today so I had to switch to a smaller project. I made some plates out of 3/16 cold rolled to get started on my transfer case shifter. My plate will use two of the NV4500 tail housing bolts and then tie into one of the top plate bolts on the shifter cover. First I fabbed up a connector for the shift rails on the NP205 as mine didn't have one. Simple enough but I wanted it strong. 3/16 steel should do it. Then a plate that angles around the tail housing to use two of the 1/2" bolts that connect the tail housing to the main body of the transmission. Next I cut off a P.O.S shifter from an old jeep transfer case I had in the scrap pile. This was fit and welded to a 1/2" cold rolled tubing. Next I will cut two braces to weld to the solid plate that will support the pivot for the shifter. Inside the 1/2" tubing is a bronze bushing to remove any slop or play. I will also thread it for a grease zirk. Lastly a down leg will be added to connect to the linkage for the maximum mechanical advantage on the shifter plate of the NP205. It would be just as easy to make this a twin stick but after a good amount of thought I am not sure I will need it. So I decided to just go simple to start. Once this shifter is completed I will make a duplicate for the other side to engage the PTO.

Already had a friend comment on how overkill these brackets are. Um...yeah, it's what I do! There will be ZERO chance of flexing this bracket. I have had to bang on a 205 shifter to get it to engage before. Bent the shifter. That will not be a problem with this one.
 
Here's a few more pics of everything mocked up. Shifters installed to check for interference, looks good there. Just need to weld in the bracing for the riser and add the forward flange that will tie into the cover plate on the transmission. 1/4" bolts were tossed in the holes as place holders and to check the action of everything. Those will be replaced with 3/8 grade 8 hardware as soon as I get it all mocked up and painted. Then pick up some linkage parts in town this week to connect it all together. Maybe tomorrow will be clear so I can actually get to what I wanted to do in the first place!
