Hi all - back with an update. Since the outer rocker for the driver's side is on backorder, I started removing the passenger side quarters, etc. I've mocked up the outer wheelhouse and the floor extension. When I line up the edge of the trunk extension with the edge of the outer wheelhouse, the floor extension sticks out 1/4" past the rear tail panel. I'll need more trimming and fitting. Has anyone else had this issue with aftermarket extensions?
Passenger quarter panel removed.
Wheelhouse and floor extension removed. The tail light panel reinforcement and edge of the extension that were removed.
New outer wheelhouse and floor extension mocked in place.
Good alignment between floor extension and the wheelhouse. The alignment looks good and the inner grooves between the panels can be pulled together with clamps.
The back of the floor extension. There's currently a 1/4" gap. This will have to be trimmed and aligned for a gapless fit.
