The old floor piece came out in one large section.
The new YearOne center trunk floor section is a very faithful reproduction on the original floor.
Adam chose to remove the trunk floor supports at this point, and transfer them to the new YearOne floor section outside the car. This would be a quicker approach than having to weld them in under the car.
Then, the new YearOne panel was trimmed to match the size of the hole left in the car.
Adam installed the long arms on the HTP spot welder, cleaned the e-coat, sprayed the bare steel with HTP Weld Through Primer, and positioned the original trunk floor supports on the new panel. Then he spot welded the panels together, leaving a factory original appearing weld process.
