Unfortunately...According to another forum..."Dan S. from DHS Racing passed away unexpectedly last (year) at age 58." The website isn't available anymore and I don't think anyone would have a spare DHS modified sifter linkage to sell you.
You can watch this YouTube Video to see the linkage basic setup with the left exhaust header cover removed. At the left side, where the left fingers are pointing, is the location of the OEM adjustable spline. You loosen the clamp screw AND remove the large hex bolt in the middle of the video frame to pull the entire linkage out from the bike. Obviously, you slide it back on to the spline at a different location on the spline teeth to raise or lower the shifter peg.
You may also need to remove some of the metal material from the back of the "center" pivot point to clear the grove on the engine. Two years ago I was fortunate to buy the adjustable linkage from DHS and spoke with David then on the phone. He asked if I had "already" filed down the shifter so people do this regularly.
