There was a post on stainless arms -
"...Carlisle, PA that was offering new (Stainless) arms and blades for $40 a pair, he specializes in classic car and truck wiper arms & blades. Not sure if they were NOS, but looked a lot like the OE.
Here’s his info if you’re interested:

Might see if he's still selling these.
Also Trico 51 Series wiper arms:
51-062 length 18-1/4" to 11-1/4" with 1/2" Knurl Driver & Passenger
51-151 length 11-1/4" to 14-5/8" with 1/2" Knurl Driver & Passenger
Adjustable head angle.
And "maybe" the Trico 73-302 length 12-1/2" to 16-1/2" with 1/2" Knurled Driver & Passenger
