sory for the delayed response daz.
just remove the top and bottom shrouds around the column.
use existing shroud screws, the ig' sw' clips into place( or is held in by the wiring plug that goes into it) so you dont need to buy anything really, i cant remember if i said in the earlier thread, but it was about a 3 or 4 mm drill i used, and again check your measurements and angle carefully.
