* Generational Differences: Nissan 720 trucks went through changes over the years. The 1980 model likely has a different transmission type and mounting points than the 1986 model.
* Engine Compatibility: The transmissions were often designed to work specifically with particular engines. The 1980 and 1986 trucks may have had different engines, making transmission compatibility even less likely.
* Drivetrain Changes: Nissan may have altered the drivetrain layout or transmission mounting points between the 1980 and 1986 models.
Recommendations:
1. Check Your VIN: The most accurate way to determine compatibility is by checking your Vehicle Identification Number (VIN) for both trucks. You can use online databases or contact a Nissan dealer for this information.
2. Consult a Mechanic: A qualified mechanic can inspect the transmissions and determine if they are compatible and if any modifications would be necessary.
3. Look for a Replacement: If the 1980 transmission is not compatible, focus your search on finding a transmission specifically designed for the 1986 Nissan 720.
Note: Even if the transmissions look similar, there could be internal differences that could cause problems if they are not a direct match.
