Knock Sensor

I recently purchased several new knock sensors. I bought them with no packaging so I don't know if they are for a 305ci or a 350ci. Is there a way to check them? They do have numbers on each. (GG-66203 3270)(66206 01341) (10456288 4170-2F) Is there a website that I can use to look up the part numbers? Is there any physical difference between the two? Thanks for the help.

not sure there's much difference between the two. i'm using a 305 knock sensor in my 350 and it works fine
