The starter is either on the right or left side of the engine down low near the transmission bellhousing.

When removing starter, note if any shims are used between the starter and mounting surface. If shims are found, reinstall in original locations. If starter is noisy during cranking, remove one .015 inch double shim or add one .015 inch single shim to the outer bolt. If starter makes a high pitched whine after engine start, add .015 inch double shims until noise ceases.
