If you have people in the back seat of a Dodge, the extended cab will have the least space for them, then the quad cab and the crew cab the most.

The Chevrolet Silverado comes in both 2 door and 4 door models. The regular model has 2 doors, the extended cab has rear access doors and the crew cab has 4 doors.
The doors from a 1992 extended cab Dodge Dakota are generally not interchangeable with those from a regular cab Dakota of the same year. The extended cab doors are longer to accommodate the additional space and seating. While some components like hinges and internal mechanisms may be similar, the overall fit and design differ, making them incompatible. Always check specific part numbers and consult with a professional if unsure.
