To be certain, you need to check one of the following:
* The owner's manual: This is the most reliable source.
* The wheels themselves: The bolt pattern is usually stamped on the back of the wheel.
* The vehicle's data plate: Often located in the glove compartment or on the driver's side doorjamb.
* A Dodge parts catalog for 1970: These can be found online or at some automotive parts stores.
Don't rely solely on general information; verify it using one of the sources listed above. Using the wrong bolt pattern is dangerous and could lead to wheel failure.
