should I buy this?

[AzCivic]

i dont get it...it says its for civics and for del sol vtec's but arent the radiator fittings for the civic are smaller than those for the del sol vtec, which is the reason when people get b18 swaps they get the del sol radiator.

I'm really not to sure i just remember reading this way back:
