clutch parts questions: w/PICS

[mattyg1405]

ok first could someone verify the 4.5g rivets part #? ive included a pic below of what i was sent im not expert but they look just like the stock 3.6g in the middle that came on the weights ive installed one and now im gonna see if i could get my hand on a gram scale tomorrow to make sure but my gut is that the pics below are of 3.6g rivets but idk if anyone can verify what i have i would greatly appreciate it ...

also is the groove worn into the clutch cover normal? am i missing anything?
and where do the engagement shims go ?

is the bushing everyone says be careful installing the one that slides on the shaft?
