Thank you all for playing what's in the box! [It's amazing how many Swift parts are

The boxed item came from member bbowens, who is everyone's favorite rare Suzuki part seller! For those reading my RHD Cultus project thread, you may recall that I hired a local repair shop to install the North American spec. parts needed to pass provincial vehicle inspection.
When installing a center mounted stop light, the shop thought it would be okay to just cut hole(s) in an existing JDM trim panel part instead of requesting that I provide them with a North American part.
So unhappy about the bodge, I photoshopped a repair to the damaged trim panel part I was looking for (shown below) to bbowens and crossed my fingers that a new JDM part could still be had. (North American grey color part from a Metro shown at top, [digitally repaired] JDM part shown at bottom)
