"my 2012 Notch..."
Not to worry, you can do what I have done for mine...
I have the guylines coming out via the vents . They are attached to the grosgrain ribbon that holds the grommet.
I then glued ,using silicone, the two extra fly ties so that I can open up the sides , the same way the existing one are in place.
To glue ribbons/fabric to silnylon you first smear undiluted silicone to both surfaces.
Let it cure for about 15-20 minutes then press the two together and leave them under pressure (put some weight on it) for a few hours.
It will take a couple of days to fully cure.
This is not for guyouts or parts that have a lot of tension on them.
