In channel window vent visors?

Hello, you mean the rain-gaurds? If so I would recommend the mitsubishi made ones. If you mean aftermarket sun shade or something different I'm not sure.

I found mine on ebay and it ended up being a real Mittsubishi dealership in Florida, Daytona I think. They were about $50 more than other brands but they have matching chrome for the window trim and that makes it worth it haha.

Those do look good, I see there are different styles. I like your design better actually probably easier to remove if you had to.
The Mitsubishi ones kinda go in the channel partly but also rely on 3M sticky tape and otherwise attaches directly to the existing chrome window trim.

Yes, these are much easier to remove if need be. I find a little heat from a heat gun softens the 3M tape to allow removal and then the skilful use of an Exacto or Stanley blade to remove the bulk of any remaining tape from the body leaving a thin film where possible so as not to damage the paint. Finish off with a rag soaked in kerosine will soften the leftovers and remove all traces of the glue from the bodywork. The kero is also a good way to quickly remove any grime build up under the part without marring the paint surface.
