If you have access to a machine shop/lathe, then I have a 2003 Stinky frame that might be an option.
The original seat stay has a crack, but I have a replacement set from CRC. There are no spare 03 Stinky seat stays available any more, so this is from a different Kona, but the replacement is the same length. However the stay is wider at the top than the original.
So… if you are up to making 2 wider spacers for the main rocker pivots, and a wider set of mounting hardware for the top shock bolt then happy days! I had planned to get this done but have never got round to it.
If anyone is interested in taking this on, get in touch and I'll send some photos to show the work needed.
The shock is a Fox vanilla serviced and custom-tuned by TFT. It was the best suspension setup I've used in the alps. It was a great bike.
