Having no luck buying Weatherstrip, some vendors won't ship to me in California. Looks like the part # is EC01-62-761F. Do you know of a source or after market weatherstrip that would work?

 

Check again? Their is no restriction on that part. At least if you are going to authorized Mazda parts departments like Reall OEM Mazda. I also noticed it shows as a discontinued part?
So if you are looking at a none Mazda vender selling parts then I can see that they simply don't want to mess with the BS politics that out dumbarse gov places restriction on items sold in CA.
Trust me I deal with this kind of BS weekly when getting some parts for customers in the service shop as well as my own parts I want or need .
