Dually dodge truck
According to Wikipedia, the so-called "Dyna-Trac" dual-rear-wheel option on D300 pickups with a 10,000 lb (4,500 kg) GWVR was first offered in 1974. It should have a Dana 70 differential.
Here's a picture of my '78 D300 dually. I should think that a '74 would be fairly similar, although there was a bit of a restyle in '78.
