A few months ago, we showed how to rebuild the rear window channel and weatherstripping areas in this '68 Road Runner. The car had been improperly stored for years and required a substantial amount of metal replacement to the rear half. Owner Ed Blankenship chose Wize Guy Rod & Custom of Jonesborough, Tennessee, to apply their considerable metal-working talents to the car.
One area that often gets rotted out due to poor storage is the rear filler tray or Dutchman panel, which fits in between the rear window support and the upper rim lip of the trunk opening. The replacement panel, available from YearOne, fits well in this B-Body application, and we are going to show you the right tricks to remove the old version and install the replacement so it looks good as new. Taking the time to do this right will help ensure that the trunk seals well and the rear window area is not misshapen.

The rear filler tray of our '68 was rotten from the rear window's weatherstripping leakage. It would need to be replaced.
The rear quarter-panels had been removed, which made work on the under-part of the new panel easier. Also, the trunk pan was previously replaced. Having the firm, steady work platform of a fresh trunk floor will make the rest of the bodywork go easier. It would be very unlikely that rust or damage serious enough to require rear filler tray replacement would not also necessitate these others steps. Just don't hang those quarters before doing this part of the job.
Somebody with decent welding skills, common air and hand tools, and patience should be able to get this part of the restoration done without a great deal of hassle or additional mechanical support. Note that this part of the process was done as the window channel areas were being rebuilt to ensure straightness and alignment.
As you will see, the primary factor in achieving excellent bodywork results is preparation and patience.

The first step is to make sure all the weatherstripping rubber is out of the rear window opening-you don't want it anywhere near the welding areas. This will make finding the spot welds you need to drill a lot easier. You can do this quickly with a torch if you want, but it really stinks (especially inside the shop), so the hammer and scraper method was used.

With a cut-off wheel and a reciprocating air saw, the old tray is cut out approximately 1/4-inch inboard from the factory seams, leaving the outer edges of the tray attached to the car at both quarter-panel sides.

Next, the inside edges of the old tray lip are cleaned to reveal the location of the factory spot welds that will need drilling.

After drilling the spot welds, it's time to test fit our new piece. We'll tell you right now, very few sheetmetal parts from any manufacturer will be a perfect fit due to the tolerances of the OEM production assembly, so plan on hammering on that virgin tin a little. The old trunk edge is still in place.
