I've searched and not come up with any hard data. Site search engine is kaput, I think it's a 70 or 80 dana, special width? Seems like it should be narrower than a standard axle, any thoughts?

 

They are all D80's. They are narrower than the pickup dually, but I think they are wider than the SRW rear end. PM 1-5-3-6-2-4, he has one, he could probably give you the measurements for it.

 

Thats correct.

 

Same truck just no bed, and usually a sparser interior lol

 

I have a factory cab/chassis Dodge dually with the Dana 70 rear axle. Would a Dana 80 from a 2nd GEN cab/chassis bolt right in as a whole axle replacement to my Dana 70? The Dana 80's can handle a whole lot more power/torque then the 70's right?

 

That's what I was getting at. I'm ditching the stock 6' bed for a flatbed and would like to add a dually rear without too much extra width.
