Headliner sail panel who's installed these or not?

[2quick]

So I bought a new bow style Headliner for my 66 Satellite and it came with 2 vinyl covered cardboard sail panels but the original headliner was one piece. Also the new headliner has enough material to cover the sail panel area on it's own. So has anyone done this before and if so did you use the sail panels or not? Bought it from Year one can't remember who makes it.

Got my headliner from year one as well but without sail panels.
I don’t know much about correctness on pre-68 headliners. But I recall I’ve read somewhere 68 models had no sail panels.

Can anyone second this?

there should at least be thick dense cardboard sail panels to hold the shape of the headliner in that area

Yes, these thick cardboards go behind the headliner and are not visible.
But are the fabric covered sail panels place above the headliner factory correct for 68 (and earlier)? I think they came up in 69 with it.
