Nice, I need to make one of those. It will help with the rears too, they are tough to reach and since the adjustment knob was rusted a bit I need some additional leverage to move it.Good to hear.
Since you do have the Konis, you may have found that the little plastic adjusting tools leave a bit to be desired. I know I did.
This was easy to make and use. Just be extra careful/gentle when re-zeroing the adjustment against its stop because it does give you a whole lot more leverage..
