WTD- Shimano M900 XTR granny ring spacers

The genuine M900 inner ring spacers have 2 'rings' around the outside and I was pretty sure thy're 5mm even. I'll pull one off one of my cranksets and measure it...
 
I dont have any original so I can only "guesstimate" the correct require length. the 6mm I put in look way too long.. I'll take mine off again & re-check. thanks for everyones efforts for such a seemingly trival part :D
 
Bolts are M8 13.5mm
Spacer are 5.3mm


EDIT to add you can see the rings mentioned on here

I can double check the length of the spaer if needed thouhg.

That was from the FC-M900 blown out diagram

EDIT 2 to add the diagram.
Only difference between Ti version : crank/bb bolt was Ti and the other bolts Alu.

thanks for info :)

hmm, maybe it IS chainring later, i'm using NOS middleburn.. purely as thats what i've got! maybe they're thicker meaning they require even thinner spacers.. i'll dig it out & check..
 
as i said above i can supply any size using the above combinations of what i have ...i understand if you want the original parts though for the tomac..

i'm not that worried about original c.ring spacers :) some of other parts are totally correct, headset for example :)
the m'burn ring is whats throwing it out, its much thicker than the shimano. (another non correct part ;) :LOL:
 
Does the middleburn have recessed spacer parts? the SG rings do and may knock the thickness down to 5mm or a little bit less.
