Interior components rarely come with instructions.  Parts such as seat covers or headliners are intended to be installed professionally, where the installer is skilled and experienced in the field.

It is still a good idea to have the appropriate service manual (Fisher Body Manual for GM) or Plymouth/Dodge Service Manual (or Body Manual for Mopar) for the specific vehicle where interior trim work is documented.  This manual will prove invaluable in working with your interior.

Assembled vs. Unassembled

Door panels:
Unassembled door panels need parts of the original door panel, or replacement pieces to complete them, typically weatherstrip, upper support plates and accenting trim.
Assembled door panels generally have the structural support backing,  accenting trim and weatherstrip pre-affixed onto them.

Note: Door panel emblems, door handles, arm rests, etc… aren’t considered trim.

An assembled headliner will contain the sail panel boards, whereas an unassembled headliner
will not.  In both cases, the headliner is sewn up to accept the bows.

Hardboard headliners:

These headliners are available either pre-covered, or uncovered.  In addition – the material is available to cover an existing board.

Headliner glue:

There are 2 types of headliner glue available…. the glue in a can is for bow style headliners.  We carry this glue as part # HGLUE.

Headliners that are secured to backing boards are installed using a spray adhesive.


You can determine which interior was originally offered on your car by decoding the interior trim code.  It is contained in various places depending on what type of car you have.

These codes are decoded in depth in the Decoding section of the site.
