Eldi, the lid bolts are reusable, so are the black plastic retainers. There are no flat washers

However the blower to head bolts are single use, buy kit 12679527, it includes the gaskets, TTY bolts along with both the flat and black washers.

- Charge Air Cooler Cover Ball Stud : Qty. 4
did not see these in the drawings or on my car (2020 ZL1)
- Charge Air Cooler Cover double Ended Stud:  Qty. 5
11610126
- Charge Air Cooler Cover Bolt:   Qty: 11
qty 15 11611992
- Plastic inserts: Qty: 20

Thanks Geoff !
I think that the 4 Ball stud bolts are not correct for the LT4 SC lid (this is why you would not find them for your ZL1). I think that they are used in conjunction with the plastic engine covers (with the "Camaro" logo) on the LT1 /SS. The covers plug on these ball-ends.
Plastic retainers! Valuable information. I could not find them in the drawings, but know that they must be used with the lid bolts and studs. Where did you find their Part# from?
