what proof do we have that 1969 383s came with chrome Valve covers?

I believe someone is reproducing them. I just cant think of where I saw them.

AMD sells the 67/68 version in chrome. You can get a set for 69 RR or such and have them chromed by a third party! Course you have to coat the # 7,8 plug wire tabs afterwards and right side harness wire tabs to get it right!
