Thanks for the good words. I should be able to get the diesel stuff sorted out as I have the factory service manual for the original truck my engine and transmission came from, the original complete harness, all the way down to the heater/AC controls, and the complete engine manual from Cummins and complete transmission service manual from Allison. They are helpful on the PW site at figuring out placement and design of the intercooler, and some of the suspension changes necessary for the heavier engines.Steve K.

There have been some really nice and neat diesel conversions done over at the Power Wagon site, does any of their expertise help you in figuring things out?
With your skills and knowledge, have you found a possible way to end up using the original 5 lug wheel and axle bolt spacing?
Please keep posting pictures, etc. as this is one of the more interesting topics to follow! Steve K.
I looked into keeping the lug pattern but the original wheels are not likely to run straight and true at the speeds I plan to run this truck. I have looked into making adapters for "parade appearance" so I can bolt the stock wheels and tires back to it. We shall see how those plans turn out.
As for the axle... Here is what I ended up with.
Set up the housing with the alignment bar.
Pressed the machined knuckle/tubes into the end of the housing and locked down the end tube alignment pucks. Set my caster to 10 degrees relative to the pinon angle of zero, so that I can raise the pinion towards the case a few degrees and still have caster in the 5-7 degree range.
Had my wife come help spin the axle housing in the rack while I welded it up. Also note the plug welds for that "just in case" factor.
Let it all cool, removed the alignment bar and this is what I ended up with. A nice straight, custom front axle housing that still uses a round center, removable third, and is "similar" to the original axles but uses more modern outer hardware that has strong disc brakes, better steering, and is all set up perfectly straight so that I don't have to worry with a bent housing causing a wobble or shake. Not to mention this axle is about 40% stronger than a stock Dana 60 and about 60%-80% stronger than the original dodge axles so that it won't even raise an eye to the weight of the Cummins hanging over top of it.
