Spent a lot of time today calling various my local body shops and parts departments for quotes, looked up prices for aftermarket parts, shared experiences from fellow owners on forum/social media. Finding out the spoiler isn't compatible with the USDM GT trim last night was a bummer, but I have already ordered the TRD spoiler so will have to just continue jumping with both feet in

So in summary, I have listed the duckbill spoiler options for us Kouki USDM GT owners from cheapest to most expensive: (My numbers are based on either US based retailer USD costs or what I was quoted in CAD converted to USD)

1) Trunk trade with someone in your area with a base model in the same color code looking for a trunk trade for one with a 17+ spoiler Cost: $0 + price of spoiler (TRD pre-painted rear trunk + side spoilers = $450 USD shipped to North America)

2) Versus CF spoiler - covers all '17+ spoiler holes; single piece does not come with side spoilers. Cost: $580 USD shipped to USA

3) Modellista Kouki Rear Spoiler - covers all '17+ spoiler holes; 3 pieces including side spoilers like the TRD aero spoiler + optional side spoilers; available pre painted in D4S, K1X, and M7Y. Cost: $810 USD shipped to North America

4) New base model OEM trunk lid + paint job - Swapping everything over from the old trunk to new trunk seems pretty straight forward to be able to DIY. Cost: trunk lid - $418 CAD (~$300 USD) + painting the lid - $450 CAD (~$330 USD) + cost of spoiler (TRD pre-painted rear trunk + side spoilers = $450 USD shipped to North America)

5) CF trunk - cost: $850-900 USD + cost of spoiler (TRD pre-painted rear trunk + side spoilers = $450 USD shipped to North America)

6) Weld fill the hole + repaint existing trunk lid - Cost: anywhere from $800 CAD to $1200 CAD + cost of spoiler (TRD pre-painted rear trunk + side spoilers = $450 USD shipped to North America)
**The body shops I called to get a quote for this job all said it really is not worth going this route as the panel is quite thin and there is a risk of warping if you want to go with this choice and they will not be responsible for warping. These were also the same bodyshops that quoted me the prices for painting the new trunk lid**

Obviously if you have the welding skills to attempt patching the hole yourself without warping the lid that'll be by far the best choice. The above options are all for those who don't possess such skills

There are also super cheap non-clean/professional-looking options such as using plastic plugs/stickers over the holes to seal them and painting over them with touchup pen. Some people have also mentioned vinyl wrapping after sealing the hole from the bottom up with filler.

Right now i'm leaning towards option #3 since I'm in Canada and the cost of Versus spoiler + shipping with the weak CAD will make it more expensive than getting a second trunk lid and painting it.

EDIT: added Modelista Kouki Rear Spoiler
