So after doing more research , I hope I have the right answer ? First it"s not copper its brass ,

Assemble thrust washers. Place one small and one large diameter cup washer on work bench with
open end up. Place one thrust washer in each cup washer with brass side facing up. Apply a coat of
bearing grease to each brass thrust surface. Invert large cup washer (with thrust washer) and place on
top of small cup washer (with thrust washer) Might help the next guy
