69 z28 carb Nuts and washers

[69z28302]

Was wondering how the carbs came from the factory. Studs Nuts & flat washers, or lock washers, or no washers. Any help will be appreciated.

Mike,
69 AIM UPC Z28 A3 shows only production nuts being used.
Others on the site could verify that being correct.

No flat washers or lock washers - just the nuts; I use thin flat washers to spread the load, but the factory didn't.

Thanks guys. I thought there weren't any washers. I think I'll a least put some flats on it.
