Thx. Randall, You corrected me with the part no. My parts book for sure
shows WP08 as (2)

By the way,  i have noticed what in the USA is called a hex cap screw. "A *hex
head cap screw* is a six-sided bolt with a trimmed *hex head* and a washer
face on the bearing surface" Most of my screws and bolts for the Triumph
have this washer face. Do I really need an additional washer or is the
washer needed to spread the load?
