Any of the on-line Mazda parts sources will have the part numbers for the wiper refill. Ebay is a good place to buy them at a low or zero shipping charge. Many dealerships use eBay for parts sales.

 

Finally found an alternate to OEM, after searching for 2 years.

The Bosch Envision has the right adapter, I only know after another forum said the Envisions work.

I'm not sure if Bosch has added the adapter to their Icon pack or anything else. I tried the Icon over a year ago and it lacked the right adapter. I also tried multiple Rain-X types (my preferred brand) with not luck.

The Bosch Envision is the first alternate I've found to OEM.
