I had a 99 silvy model that came with a jetski (I got it then..well before I was driving) and i had coils in the front (they came from identical clicky pens) and some stought plastic that had some flex in the rear..it was awesome. no pics tho..its in storage somewhere.
I was thinkin about the clicky pens but since i used to make some box calls, loli have a bunch of short but wide coils that are stiffer.
