Anthony - come pick the dash up and pay later (i need space)
As for the vents - if your going to replace them just pull them out.
Centre one has 4 clips top and bottom, Passenger has 2 clips top and bottom.
See pic.
Newies will slide in and clip into place.
The screws I saw previously just hold the AC/Heater plastic piping behind the vent to the dash. Dont actualy screw into the vents.
My pics comming tomoz
