Question about air dam.

I hit a headlight on the interstate and it pretty much destroyed my air dam, followed quickly by ripping out part of the splash guard, which in turn pulled the drivers side splash guard into the wheel. Needless to say I'm doing some repairs. I've found all the splash guards, but in looking at the air dam I can't seem to find the OEM air dam. I think the part number is F151-51-9K1A. However, when surfing ebay I keep finding this part number, F151-V4-900F-64, such as here: EBAY Listing



I guess my question is this, how does that ebay part fit in comparison to the OEM? It looks like that part has some sort of sides that the OEM does not. I'm not sure if I can just remove the broken one and replace it with that one from EBAY or not. Anyone know? Does it just sit lower and that's what the side flairs are?
