Somewhat still on topic, in this pic:
Richard is showing a star type lock washer.
The Osborne Assy Manual is not showing the number for the washer as all I see in this washed out section is the number "8."
However, a revised August 67 Illustration Section 20 does show the complete number as 34808-s(X-67).
Jim's spreadsheet shows this number to decode as a "Washer,Lock,Split."
The reproduction hose kit includes a split washer.
I can't find my re-plated rear brake assy right now to look for witness marks. What should it be for the majority of the 67 year?
