Does anybody have the track width information for the D100's? My internet searches have come up empty. This is related to my Dakota post question. I am contemplating putting that 9 1/4" from a Dakota under my pickup noted in the title. I believe it to be little wider than the 8 1/4 in it, but wonder how it compares to the front track width. Getting accurate measurements has not happened yet. Prelim measure has the spring perches very close to the same.
