@reebs - The washer is .25 thick (height) with a slot filed down to .236 thick. None of the measurements relate to the width. You do however want the slot to be in line with the stock slot of the derailleur.

The lip is part of the stock XTR derailleur. It does give the square brass nut some nice purchase so it doesn't rotate when you tighten the cable down. 6mm is the magic number but the cable needs to stay lined up with the stock line pull. I originally started this mod with a stack of washers at first and quickly found when the cable inevitably rotated away from the stock pull direction the pull ratio was off and the shifting suffered.

@ A300hp - I was pretty psyched it was so successful. And just for the record, this was not my original idea. Steevoo on MTBR pointed me in the right direction here. His specs were spot on. He deserves all the credit for this one.
Yes - the drivetrain is sram 9spd aside from the rear derailleur.

@Grelax - Its close without mods, but depending on how you set the tension on the cable either the top or bottom end is off. Its marginally acceptable without any changes, but the whole drivetrain will wear faster and the mesh will be off at either end of the cassette. Thats what I have seen anyway. I haven't tried any 8spd shifters yet. I can imagine the outside width of an eight speed chain might be an issue with the 10spd derailleur?

Roughly six months on the XTR shadow plus in the other pic. Zero issues. Ran this Zee this weekend. Flawless.

Sram x9 nine speed. Currently only 10speed clutch derailleurs available. Otherwise I don't see the point. Further reading here... http://forums.mtbr.com/drivetrain-shifters-derailleurs-cranks/dyna-sys-10-speed-compatability-9-speed-shimano-systems-646014.html

I actually started with a stack of washers to give it a try first. Unfortunatley the washers rotate quite a bit when tightening and make for a finicky setup. The spacer is just a square brass nut. I have a few left over from a ladder rack kit. The brass is easy to work with simple hand files, won't rust and doesn't hurt that it matches the shimano gold accents.

I'm getting near perfect shifting with the spacer. Without the spacer the pull is off enough that the shifting is good in some gears but not all. You may see a video below of someone testing some combinations without the spacer. The cursory test in the stand sounds ok but i suspect under load it's going to be off enough to get some skipping in some of the gears. Thats what I've found anyway. Also, without the spacer the window for adjustment to align the gearing is very small at best. Just give the spacer a try. The investment in the mod is minimal and reversible.

Just to be super clear the mod I described above works with 10spd mountain Shimano derailleurs and 9spd Sram shifters. Take your pick of the rest of the 9spd drivetrain(chain, cassette, front der., chainrings). You could read for days over on MTBR about compatibility of other combinations.
