I installed the " Monster Fan 290 " . Hint ::::::: If you go this route I will let you know how I installed it . I modifided the brackets that came with the fan and used the mounting of the fan shroud . I did some trimming on the shroud so it would fit over the flex-a-lite frame . I also had to purchase some longer bolts to pass through both the brackets and the shroud .
I don't have the coil # available but I did contact MSD for the proper coil .
