Thanks...I texted the guy and am waiting on WMS measurements.

I wish we had a good junk yard here...maybe I will take a look anyway...but good call on the sway bar links. Thanks

The Dana sounds like a good deal. it looks to me like a dually rear, the wheel on the left is obviously an outside dually wheel. I think the measurement difference is between backing plate width and wheel mounting surface width.

Go for a day trip, the worst you could be is wrong and gas is cheap. Just be prepared to bring it home with as many parts as you can get. If the wheel base is the same, grab the drive line if you can, spare parts are either usable or trade goods. Since you don't have your wheels and tires yet, you can adjust your tire diameter to dial in your cruising RPM. the 4.10 with that 235X85R16 tire would be 3042RPM@70.

Let us know how it turns out.

Good Luck

I was thinking our trucks are similar for sure! Good thinking on the drive line if the WB is the same!

Yeah, I am waiting on wheels/tires until I figure out the rear end. I think I am going to swap it...don't think I can handle the 5.14 gears!
