I just checked the book and to my surprise, it says the 4-Door Lid will fit on your Impala Custom.
Book states that they made 2 different Trunk Lids in '68, the Impala 2-Dr HT Sport Coupe and all others.
I have to say it is deceiving as the car has such a long back end to it, but it does have a wide space between the back glass and the trunk lid to make up for it.
