Spoiler Support legs

[Astra]

After deciding against the EVO Spoiler, i've decided to modify the standard GTE one buy smoothing off the edges and undersideand raising of my boot lid. I need to know where to get hold of some aluminium/steel spoiler supports to do this, and as its a MK2 astra hatch, i might need to attach these supports to the rear window somehow as well as the boot lip. So guys do any of you have some ideas for where to procure some supports legs and how these could be attached to the rear of a Mk2 Astra?
