I have one behind the Hemi / Passon aluminum case A833 in the silver Duster....To keep the engine angle close to factory, I cut a 12" section out of the pinched part of the tunnel aft of the 4-speed hump and replaced it with a section of tunnel from Chris Alston. Shorten driveshaft a given
I made several attempts to use it in a drag scenario and found it wasn't consistent with too much lag between flipping the toggle and the shift. Great for super slab cruising over 65 MPH though.
