The cables are considered a wear item and highly doubtful they'd be covered.
They may ship you a freebie IF you can show a failure at the Swedged end due to over (cut wires) or under (slippage) swedging.
They do sell all the various cables for all the Maint lifts and your Storage lift as well, See page 32.

Making cables using a local vendor can work IF they use the correct Flexible cables for your application (they come in several turn radius ratings).
