they look close to the 69 Camaro but the dr side rear spark plug wire bracket looks wider then on a chrome set
I have.
Many of the BB valve covers look similar but have small difference in the spark plug wire brackets or temp sender wire brackets and locations or the shape of the dr side rear cover.
The dr side cover is trickey because brackets had to be correct to get around the wiper motor, power brake vac line , temp sensor location, etc
