Long story short. I used the stock bottom bracket, fabricated two upper brackets to tie in to the existing upper clips (pretty simple just some flat stock with a 15 degree bend in it to hold the fans tight to the radiator. I trimmed the ears and some of the fan shroud off with a cut off tool and the fan slid between the end tanks and flush to the radiator. Once it is in you can not see the trimming of the sides as it is hidden by the end tanks.
