Is a duelly dana 70 or 14 bolt the same as a single wheel truck?

I believe they are narrower than single wheel trucks.

I know that the dually dana 70 is wider than a single or a dual wheel 14 bolt.

I better make my last post more clear. I was talking about the dana 70 that is in chevy dually pickups.

Duallie trucks with pickup boxes have very wide axles and weren't made until 73. Duallie trucks sold as cab/chassis have narrow axles. 67-72 duallies have the same axleshafts as single rear wheel trucks. Every 73-up duallie PICKUP I have seen had a Dana 70.

Yes, Duallie is correct. The pickups with regular beds had dually axles the same width between the drums as the single wheels. Vehicles such as the cab/chassis models, bread trucks, motorhome chassis, etc., had a narrower rear end. They have the same spring perch width, but the drums are almost touching the springs.
