* Specific Trim Level: Different trims had different axles, suspension components, and potentially different ratings.
* Transmission: Automatic or manual transmissions affected towing capacity.
* Options: Things like added equipment or optional towing packages significantly altered the rated capacity.
To find the exact towing capacity for *your* specific 1987 Mazda Mighty Max 2.6L, you'll need to:
1. Check the Owner's Manual: This is the most reliable source. The towing capacity will be explicitly stated.
2. Look for a sticker: Check the driver's side doorjamb or the glove compartment. There might be a sticker listing the vehicle's specifications, including towing capacity.
3. Consult a Mazda parts dealer or service department: They might have access to historical data based on the VIN of your truck.
Without this specific information, any number given would be unreliable and potentially dangerous. Never exceed the manufacturer's recommended towing capacity.
