No 9", but they do have 8" and 10"... New Port Engineering | Product categories Wipers (newportwipers.com)
Not sure about where you are, but here in New Zealand, insert replacements (rubber only) are available to suit most cars. I find the right end section shape, and cut to length..
Use to keep trico refills behind the counter when I worked at oreillys. But that's been over 5 years or more.
@57 Fargo @inthweedz beat me to it, but I used to do the same when needed. Match the cross-section of the rubber wiper, and cut to length.
Looks like you have a Trico Rainbow wiper blade in there currently, like so: https://www.ebay.com/itm/235394328771 As suggested, get a good close up view of the cross-section (or just view it end on) of the rubber blade itself, find an older blade with a matching profile, and trim to length. You should be able to bend up one of the end tabs on you wiper blade body to get the old one out.
https://www.tricoproducts.com/products/factory-performance-wiper-blades/trico-cl***ic They have blades and refills on certain models. Oreilly can order them in from the warehouse. I haven't seen any stores local stcok them.
You want to be careful when doing this. The blade frame that holds the refill can wear out at the little 'channels' that hold the refill. If one breaks in half while in use, it can trash your windshield in nothing flat. AMHIK.... Make sure those channels aren't too worn, that stainless isn't very thick.
Every old car/truck I drive I have done this with, to me it’s a given to ensure it’s not going to fall apart.
9" is a common size for rear screen wipers. Should be easily available at the parts store. Look for 230 in the part number.
I just picked up a pair of 10" from Orilly's a few days ago, had them in stock in the store. I found out I could order them on line to pick up at the store, and save $3 each over what they cost to walk into the store and buy them! According to the salesperson, the store can't even match its on line pricing. I'm thinking that is BS, but that was the way it went down. just a heads up.
