After losing an ill fitting aftermarket side vent at speed I decided to go with a more dependable option. Don't really care for the 03 vent style so I did a little altering to an older style side vent.
Picked up a set of these on Ebay $29 a side. If you don't see your color ask. 2 days after I bought the white ones the same seller posted a mint set of red ones.
Removed collar and cut off slats:
Added mesh to collar and painted the vent red. Dont have to worry about fit anymore.
