Is it possible to get a modern bayonet mount adapter? That would at least give you possible wiper blades so you can drive in the rain while you find OE style replacement blades.

It looks like British cars use the same blade mount as the 240Z.

Here's a testimonial from @jfa.series1 that they fit the 18 inch frames.

if it works, it's not bad. I pay $30-40 for beam blades every year or two after they get chewed up by winter ice.
There has to be a company making them- they were popular in the 1970s-80s on muscle cars and trucks, like the Camaros, firebirds, and the F-150.

Anything regarding Trico or Anco is gone now.

Does 44-180 refere to anythoing, like 180mm length? 180mm is only 7 inches? The 280Z has a blade of 17 inches

I think you were on the right track here, just the wrong end of the p/n. 44 centimeters equals about 17.3 inches.

Thanks for the tip. Now I just have to find some wiper catalogs, to cross-reference them and cars.

We used to just grab a TRW book to look up stuff, like steering parts. Trico and ANCO references are NLA.

I may need to take a tape measure or a wiper blade to a salvage yard or car show?

I do knowthe blade insert has a 5/16 width and is 18 inches long.

Sorry, can't answer the question as I don't have 17 inch frames. My frames are just under 18 inches and I would use these blade inserts.

I found a set: Trico 44-170!

I bought them at a local Federated Auto Parts store- $10

but how do you get the last 1cm in, and hook the clip into the frame- very carefully? 😉

These inserts have a plastic backing with grooves to fit into the claws on the frame, but the end without the clip is slightly short of the end of the rubber (to compensate for the clip, IMO.)

Since these are the most recent made (1993), i will presume the plastic backing won't crumble after 1 summer.

In the meantime, there are a couple sets on order from various places mentioned here (you can't have enough spares)

The guy at the AP store (Federated) insists that the 170 in 44-170 means 17 inches, not 170mm, and not 44 cm.

Trying to fix the internet is a hopeless task.

Walmart thinks it's a 22" vehicle.

OK... but 22 inches long?

Amazon says 17".

Take the old ones off and go to the parts store. Use whatever matches.
