Rear window clip

[blueg33]

I have the Raceproved clips, they come with a nut and bolt to replace the self tappers although at first I just reused the self tappers. One of my self tappers was pulled out by the leverage of the new clips, so it took me 10 mins to replace all the self tappers (didn't even need to drill I just used the holes for the self tappers which go right through). Its now all nice and secure

I have to say I've always found these clips very expensive. Why arent there any cheaper clips available on the market? very low production hence the price?
