More trouble with my controls!

[cliffpaul2]

I'm at the end of a frustrating day. My Sturgeon fishing trip was interrupted when my boat got stuck in reverse. I took a closer look at the controls and found that they had been band-aided together by the previous owner. What is missing is a metal insert that keeps the cable sheath from sliding while the cable slides in and out. Here is a photo of the area where the insert would go:


And here is a shot of the other cable that shows what the broken one should look like:


And here is a closeup of the insert that I need:


Does anyone know where to get one of these? Does anyone have an old set of controls that I could buy for parts or to replace my whole setup?

This is a factory set of controls (I'm assuming) that is on a 1980 model. Maybe it's just time to replace them. I don't know...

Thanks in advance for your advice on this!
