To begin the tuck, Schmidt started work on the inner body structure. From the bottom of the inner rear quarter where the below the decklid panel bolts in place, he measured 5-1/2 inches upward from the base adjacent to the mounting holes. The incision was then made with a cutoff wheel. He then measured inboard and marked a graduated 1-1/2-inch wedge pie cut from the base upward and removed the marked area with a cutoff wheel. To allow movement of the panel for the tuck, an adjoining section of the rear sub rail was also removed. Finally a 7-inch measurement was then taken from the outer reveal base up and a 3/8-inch pie cut was marked and removed away using a cutoff wheel. The areas were then deburred and cleaned up. In order for the measurements to work effectively, they were matched to the outer quarter-panel using a square to establish and create a mirror image of the internal pie cut. The area was then marked with 3/4-inch masking tape to confirm the required removal. A cutoff wheel was used to make the incision followed by a matching 7-inch cut complementing the internal one. Finally a graduated 1-1/2-inch pie cut was taken from the exact area on the exterior of the quarter-panel. All areas were then deburred with a disc grinder, topped with a 40-grit disc and flat file.

With the initial incisions completed Schmidt began working the steel on the tail with a body hammer and assorted dollies, gradually moving the panel forward, complementing the pie cuts. This step takes time and patience to gradually move the metal. At this time the rear body panel was bolted back into place. Continuing, there were a number of relief cuts required to relax the steel and allow the tuck to continue movement forward. With the 3/8-inch pie cut closed atop the quarter-panel, a measurement of 2 inches depth with 1-inch-wide increments were marked for relief cuts. The cuts were made using a cutoff wheel and TIG-tacked first to hold them in place. This allowed the curvature of the rear quarter-panel to be worked back into shape. A body hammer and dolly were used to assist in reworking the steel back into shape. The relief cuts were then final TIG welded, with particular attention paid to cool the panel between welds to avoid any metal warp from excessive heat. Finally to allow for additional movement the wheelwell area received a graduated 1/2-inch trim tapering off to 0 inch. The reveal line was then TIG welded. A disc grinder topped with a 50-grit disc was then used to knock down all the TIG welds followed by a flat file to complete the job. A tip from Schmidt was to use a section of welding rod to roll across the quarter-panel to observe any needed adjustments for high and low spots and to follow on the adjustments with a body hammer and dolly, completing the tuck. This step can take time to finesse the panel to perfection.

The final step in completing the job required the reshaping of the wheelwell body reveal arch to give the area a perfect balance. For this Schmidt secured the rear half of the wheelwell template back in place. He followed by marking an area for removal and proceeded using a plasma cutter. The area was then marked using 3/4-inch masking tape for removal of a portion of the inner wheelwell to allow for the re-proportioning of the body reveal. Once the opening was completed, the area was deburred and prepared for the next step. A template was created for the extension of the body reveal arch and inner wheelhouse area and was transferred to 18-gauge steel flat stock. The new section was then TIG welded in place, followed by finessing with a body hammer and dollies to complete the new look. Final grinding and filing left the reworked body reveal arch, inner wheelhouse, and quarter-panel looking factory fresh while completing the look by adding just enough speed to the rear while removing the once present ducktail.
