The Durango pan might be fine in a van, but I don't know that for sure.
The vans steering assy might need specific clearance places that the Durango pan could interfere with.
My own experience tells me that vans usually have a crapload of clearance, and the motor is hung well above the steering.
Rear drive Vans also don't have a K member like what makes us change pans for fitting in the Mopar A bodies.
