Initially we wanted to use the fore-Aft mount style the 8.9L uses in it's native habitat, but quickly realized that any rear mount design (off the bell housing adapter) would take up a lot of down-pipe real estate. at this point we're planning to use the front cross member mount out of the Freightliner as well as the mid mount from the Ram.
