I found the total length of 7.875 online. I don`t have one to measure but I remember that to be pretty close. I recall that the mopar ones had a part number on them but I may be wrong. You could use a dremel with a cutoff wheel and stick something down the tube to catch the fragments and use a vacuum to suck up most of it then remove the it. That almost seems to be the easiest solution other then maybe you have the wrong stick.
