Installation Notes and Tips

Verify engine, transmission, body code, and transmission type before ordering, since this application list includes both manual and automatic configurations. Compare the existing mount shape and mounting points to the OE-style replacement parts referenced in the kit description before installation. For best results, inspect adjacent brackets and fasteners for wear or damage during service.
