Hi Kdulf, You probably are seeing a few or several options available. You can choose the most affordable like most people do among the brand selections. The options we show should be different brand manufacturers, but it is the same exact part just manufactured by a different company. Also, we recommend referring to a trusted vehicle specific repair manual for details about troubleshooting, diagnostic and repair. Still, it is best to consult your trusted local auto repair shop or dealership for this as well if you need to.
