So here is how you determine which Door Talon will work best on your rig.
Take a tape measure, open your side door to the full open position, with just a little pressure on the door. Now measure from the inside of the wheel well to the flat edge of the door. The pictures should help illustrate how this should be done (note the arrows in the pics).
If this measurement is between 6" to 71/4" the original kit will work for your van.
If the measurement is larger then 71/4" you will want the new extended version.
The Door Talon Extended will work in either case, the extra hook just won't be used and it will not get in the way of anything.
