Do you still have the old cable ?
If so you can send it to venhill in England to do a copy or buy the bits from them and make your own last resort for me .
Venhill web site has pre made cables to buy but only list xr80 ?
I looked on Partszilla not available.
have you googled the cable part number and see what pops up.
Motion pro do after market cables they have some on Ebay .
