Can you use a starter off of 1987 2 9 v6 bronco II to replace the on an 1992 ranger xlt 4 0 v6?

No, you can't directly use a 1987 Bronco II 2.9L V6 starter on a 1992 Ranger XLT 4.0L V6. While both are V6s, the engines are significantly different sizes and likely have different starter mounting points, bolt patterns, and electrical connections. The 4.0L is a considerably larger engine and requires a higher-torque starter. Trying to use the smaller starter from the 2.9L would likely result in failure and potential damage. You need a starter specifically designed for the 1992 4.0L V6 Ranger.
