I used the mercedes fan in my 67 Coronet and it works great with the champion 3 core rad. But it is a very tight fit. A member here sells the controller so there is a nice soft start plus it only runs hard when it needs to. I'm also using a gm 140 amp alt. which handles the additional amperage. I have A/C and a high horsepower 493 and my car stays nice and cool.

Do a search here on moparts and you should be able to find all the info you need to install it.
