where to get a power antenna cable ???

My power antenna cable on my 1984 has been damaged and I wanted to know if anyone here has purchased one lately.  I have had a look around the internet and I can find antenna cables for newer ones but nothing for an 84.  If you know where I can pick one up, please let me know.  Thanks and happy driving to all.

I'm afraid you will have to replace the unit. A/C Delco makes a replacement, but with some minor modification.

Thanks once again mech...I'll start the process.
