The OEM is discontinued. Any alternative for the roof molding/drip rail molding?

 

No alternative I've ever seen. Anecdotally speaking, my roof moldings have held up well, and it has lived its life outside so far.

I was able to remove them without breaking and they looked good after a rubdown with Shin-Etsu silicone grease.

So join one of the EF facebook groups and ask around to see if anyone has them. Once you find them, clean them up and install. Should last the life of the car.

 

I have not personally used these, but someone that I follow on instagram sells new EF hatch roof rubbers through his instagram page. His instagram profile is taiwan_ef and he also has a reddit account from the same name. He looks legit and apparently sells a lot of them according to his instagram page but I would definitely do your own research before buying.
