Rear wiper inserts KR9P-67-333 and Under Shield loose on one end!

Mazda USA list it for $8
Local dealer wants $18
KR9P-67-333

Rock auto has a hefty shipping fee.

Is there an after market part that will fit? How do I go about it?
This thread seems to going for Honda 12" insert!
Maybe this honda part 76732-T0A-003 $8 from dealer!

Also the under shield is hanging loose on one end. Anyone fixed this?

I bought 76732-T0A-003 $8 with tax from Honda dealer and installed it.
Its tard (mm) longer but not an issue - it wipes fine.

What is the deal Mazda parts are expensive and dealers won't negotiate price.
They wanted $18 before tax.
