radiator identification please help

I am trying to buy a radiator but i cannot identify which one originally came with my car so i know which radiators will fit. I know that it came with either a Toyo or Denso but i canoot tell i looked all over my current radiator and there are no markings stating what it is. i have been searching all over the internet and here on how to identify which radiator is which but no one has a sure fire answer.If you have the answer please share your knowledge. I have a 1991 Integra RS automatic trans thank you so much.:auto:

They both originally came with the car. As to why there are 2 different maker, I have no clue. it dosnt realy matter which one you pick. As long as you make sure its for an auto tranny, it will work

Sounds good thanks for the reply you dont know how much it helped now i can get my rad. Thanks
