I've made a mint from selling those clips on ebay. Every time i go to a junkyard, i check the trackers and sidekicks for the clips, get them for next to nothing, then sell them on ebay for $20-$30. It's crazy.
I have bought some new from suzuki before. i can't remember the price, but considering how much i was putting my top up and down (australian summer), i wanted a good clip.
Since then, the junkyard here in seattle always seem to have a pair or 2.
