* Minor Differences: There might be slight differences in trim, grille mounting, or other small details between years. You might need to adapt some parts for a perfect fit.
* Body Style: Ensure the cab you are considering is a regular cab and not a crew cab or extended cab.
* Specific Models: While generally interchangeable within the 1976-1980 range, matching the specific trim level (e.g., Tradesman, Custom) will simplify the swap and reduce the chance of compatibility issues.
* W200 & W350 Considerations: W200 and some W350 cabs *might* fit, but there are differences in mounting points and potentially weight capacities. This swap is significantly more complex and may require significant modification. It's better to stick with a W150 cab.
Before undertaking a cab swap: It's crucial to physically compare the cabs to ensure the mounting points, firewall, and other critical components align. A successful swap will require mechanical aptitude and the right tools.
In short, aim for a 1976-1980 Dodge W150 cab for the easiest swap. Going outside that range or to heavier-duty models dramatically increases the difficulty and may be impractical.
