I'm putting some of the interior back in my '68 now, and the rear package shelf has me puzzled. I'm using the jute insulation under the board and the board just doesn't want to go with the jute under it. Do I put the jute down, then bow the board in the middle and slide it in as an interference fit with the ledge at the back window? Or do I glue the jute to the board and install them as one piece? Or do I glue the jute to the package shelf first? I know the vinyl strip at the front of the board needs to be glued to the trunk divider board at final installation, but the fit is so tight now I can't get the doggone board into place with the jute under it for mock-up. My Fisher Body Manual is no help. What's the trick to this, guys? Thanks.
