I've got a '78 510 with 16" wiper blades. It's got the original metal blades. Obvs the rubber is worn out. But the metal parts are still tight, and they kind of have a wing shape, they look cool and match the style of the car. I want to keep the blades and just replace the rubber insert, rather than replacing the whole blade with some generic modern plastic blade.

I bought some Duralast blades at Autozone and was able to take the rubber out and put it into the Datsun blades, but because the duralast insert has two metal reinforcement ribs (rather than one slotted one, like the old inserts have) they pop out pretty easily.

Anybody have a source for old school wiper inserts that work with the Datsun blades?

I have no plans to ever actually drive the car in the rain, I just want to them to work in theory. lol.
