Doesn't seem like anyone sells them anymore. I have two 60s cars that don't have the removable blades.
... or is there a solution to fitting blades on the old arms? One I could just replace the whole arm with a newer one, but the other car has those semi-parallel links that turn the blade as it arcs.
NAPA appears to still sell them.

That reminds me, I need a set, too. Thanks.
Also, these could be an option: http://www.tricoproducts.com/Drivers/WiperProducts/MoreProducts/Classic
Wal Mart has refills and blades.. got the ones that i put on my 74 Monte Carlo there, and that has the linkage on the driver's side arm like yours does...
but if you have money to burn, you could take your choice of any number of resto places..
Thanks for the links.
And of course I have money to burn. I work in entry level retail sales and I'm restoring three cars. 
And you can cut down longer blades if you can't find your size.

See my above post. Money to burn = I have people for that.
