My '83 300D has a broken adjustment nut on the Bowden cable. May be partially responsible for the car shifting at <1500 RPM.

Appears that these Bowden cables aren't being made any more. Mercedes shows 0 domestically or in Europe, and no options online for the correct PN (1263001730) for the '83 300D; mboemparts.com show one available but cancel the order as soon as it's placed.

Has anyone attempted to use a cable from the '87 300D with the same transmission number (722.3xx)? ********az has cables for this transmission, but it doesnt show compatibility w/ the '83. http://www.***************/search/product.aspx?partnumber=1263001930&utm_source=google&utm_medium=nonpaid&utm_campaign=frooglePN&utm_term=W0133-1715965&crossref=W0133-1715965&gclid=CjwKCAjw7MDPBRAFEiwAppdF9Bfpx5XycNFI95Xijz6cWED1KKZMTLKjVG2xNkzl9AHahUilRf67ixoChUsQAvD_BwE

Any other sources or workaround, other than pulling a used cable off another vehicle?
