1989 Ford Ranger ignition module bolt size?

There's no single bolt size for the ignition module on a 1989 Ford Ranger. The size depends on the specific engine and its mounting location. The ignition module could be mounted to the distributor, the firewall, or even the fender depending on the year and engine.

To find the correct bolt size, you need to:

1. Identify your engine: (e.g., 2.3L, 2.9L, 4.0L) This is crucial.

2. Locate the ignition module: Find where it's mounted on your truck.

3. Examine the bolts: Once you've located the module, visually inspect the bolts holding it in place. Use a ruler or caliper to measure the bolt's diameter and length. Also note the thread pitch (the spacing between the threads).

Once you have this information, you can easily find replacement bolts at any auto parts store. Alternatively, you can take one of the bolts to an auto parts store for matching.
