I have an old 6001 T6 from 2001 seatpost but lost the dome washer than fits between the bolt and seatclamp.
After talking to Syncros and their distributor in the U.K. who told me sorry we can only sell you a new seatpost!
I've checked DIY stores but will check machining places next.
Any tips on finding some would be great!

Replacing my short carbon post with an old mtb one.
