Common patterns for that year include:
* 5x5.5" (5 on 5.5 inches): This is a very common pattern for Ford trucks of that era.
* 8x6.5" (8 on 6.5 inches): Less common, but possible, especially on heavier-duty models or those with aftermarket wheels.
To find the correct bolt pattern:
1. Check your existing wheels: The pattern will be cast or stamped into the wheel itself. Look for a number like "5x5.5" or "8x6.5".
2. Consult your owner's manual: The manual should specify the bolt pattern for your specific truck configuration.
3. Look at the hub: Sometimes the bolt pattern is stamped on the hub itself.
Do not attempt to mount wheels with an incorrect bolt pattern, as it could be dangerous and lead to wheel failure.
