Ok guys, i fixed mine about a year ago. The plastic runners are about $2.50each and there is 2 per window. Take off your door trim ,The Haynes manual says you have to remove the regulator by drilling out the rivets but i found it easier to loosen the window guide channel, Thats the one that runs from the top of the window near the mirror to the bottom of the door then push it to one side . The clips are a press fit and the Holden guy said you need a special tool to press them on with but i used a small G clamp , about $2.00 from Bunnings. You just slide the clips into the channel , line up the holes with the studs on the lifter arm then tighten the clamp till the clips pop into place . Make sure that you use plenty of lube on the clips and also make sure that you don't squash the channel when doing the clamp up . Hope this helps you guys . Any probs just P.M me ,Cheers Dayvo
