Is there any correlation between the engine and the radiator fit

In other words does the B1 engine = Toyo 4 blade Fan/Shroud/Rad

and the B2 engine = Denso 5 blade Fan/Shroud/Rad ...

???

Very few None of the Internet Radiator sellers are asking me if I have a Denso or Toyo setup. I told them how many guys at this site warned me to be careful of fitting an aftermarket rad on Honda's with a J vin # [Toyo or Denso] set up. These sellers have told me it does not matter ... and they have not had any returns ... and that they only sell one rad model and it fits all the accords.

Of the sellers that do ask about the Toyo Denso set up, they list the same part number for the Toyo ad the Denso, so, if I were to use a credit card and ordered, via, the website, well, how would the person who takes the Internet orders know which one I needed ?


So, does the B1 engine = Toyo 4 blade Fan/Shroud/Rad, and the B2 engine = Denso 5 blade Fan/Shroud/Rad. It is the only explanation I can think of.
