I have a Griffin 'direct fit' in my Duster. It's a nice radiator, keeps my car cool and shaved a bunch of weight. However, it wasn't a direct fit. The tanks/core are fine but not the mounting parts. Not sure what specs they had but its not really close.

The way they made the brackets put it closer to to the engine than the OE 26" I replaced so I had to get the short Jag fan clutch.

Also, the way the brackets are made does not allow an OE shroud to fit without modifying it.

This also required a smaller fan blade because none of the ones I had would fit without hitting the shroud because of where it was now mounted (as opposed to the OE position). Probably operator error but while figuring all this out, I mangled the fins pretty good. No leaks as of yet though.

If I were to do it again, I probably would just get a generic rad and figure out how to make it work.
