Well I guess sending members to another site is OK if it's all in the name of Opels. Go to the ClassicOpels webite that is hosted by Yahoo. The URL is:

I've got about a dozen pictures of my Addco front and rear installation. Go to "Files" then go to "Technical Information" and there is a folder named "Addco F&R Sway Bars for GT".
I got the bars front and rear for $99 each, all hardware and poly bushing. Buy some teflon grease and goop the bushings up well, otherwise they squeak and groan like an old wooden staircase.
