2 part questions thermostat and steering

[steplift20]

I have to disconnect it from the helm to find out where the problem is , I disconnected it from the engine could not pull it out all the way but seemed very loose not hanging up at all but still hard to turn wheel I have to disconnect it from helm than push pull cable to see if it s hard I have a feeling it is the helm itself, do you know if you can just buy the helm without the cable? If not than I will have yo get the whole assembly I think it's 17 feet, can you verify the length Thanks for all the come backs
