yea I've seen in the past how you can have multiple part #s for the same part.
I found this website:
you can search my model and year, and they have illustrations for alot of the components. however they dont give the actual part #.
on a side note..........I am looking for the sensor that goes into the stock air resonator on the 3.7L engine. I found an "air temp sensor"......does that sound correct? Not sure if its for intake air temp, or exterior air temp lol.
