I am calling these 1976-77 roof panels. Does that look like correct year?

There is an early and late 76. Read the description

Well they look like the parts in that catalog listing but not clear to me what the E vs L differences are in these parts. In most industries if you change the revision to a part number it still has to be interchangeable with any other revision. If not, then you have to change the part number. I have never been sure if that was true in the auto industry or not. I assume it is, but assumptions are risky. In any case, thank you for posting that link. It gives me a reference point to indicate that the 76-77 time frame is valid.
