So... after exhausting many hours trying to get in touch with reps for Depo, Depo themselves, and even having locals in Taiwan try to approach Depo in person, they and all of their distributors who can get these flat out refuse to ship to the US. I'm even trying to orchestrate sending them to a holding facility in Taiwan that we can then just ship these to the US from there. Nope. Nothing.
The reasoning is that even though you can get them in LHD traffic patterns to work here in the US, they have not been tested to conform to DOT regulations. As such, Depo doesn't want the negative press associated with a product that may very well fail the requirements.
With that awful news, I ordered a set of OEMs for ~$446 shipped from the UK. Doing a retrofit anyways, so the RHD cutoff is irrelevant.
