Please pick apart my L78 Camaro

[68camaroz28]

Considering what I know on later years I’d believe the Heater core assembly speed nuts and ex manifold bolts phosphate instead of clear zinc, appears alternator wire rubber boot is what comes with aftermarket wiring harnesses, zinc washer under one painted water pump bolt, and valve covers as mentioned are incorrect but also aftermarket reproduction. Overall nIce find and congratulations. Much of aforementioned in posts easy to change so have fun.
