This is what i'm looking for. Just felt like this is a lot of money. https://www.ebay.com/itm/NEW-NOS-Mercedes-W113-230sl-250sl-280sl-Factory-Original-Bosch-Wiper-Blades-NEW/303543089091?hash=item46ac93f7c3:g:3WUAAOSwC7NemdbU
Always keep your originals if you still have them. You can then find some modern rubber inserts with a profile close enough to work fine. Replace the rubber inserts and for a few dollars you are done!
Little bit off wiper blades abut spot on for keeping original things that you take off the car..... When I bought my first Pagoda and it had a modern radio in it, I pulled it out and threw it away to replace it with a correct Becker for the year 1969. May as well chuck out the automated aerial too as no 40 year old car woud have an aerial that went up when you turned the radio on would it? DOH.
