It is tough enough getting those cheap cardboard replacement headliners to fit the pickups that only have one headliner bow.
Goog luck trying to fit the replacement cardboard liners to the 5 bows in the burb roof.
Even if you were able to pull it off with no gaps you would still have to deal with cardboard that dries out or absorbs moisture,gets brittle, sags and falls down with age.
I opted for the time tested leather option using the original bows on my burb.
