Replacement parts for power antenna

[Thunder]

I finally dug into my power antenna, and see that I'll need a couple things. The cable to drive it up and down was broken, probably due to bent mast sections. I've searched the archives trying to locate some gm part #'s. All I can find is for the drive cable. I think I ought to change the hollow mast pieces as well. I also have some damage to the small 12 inch piece of coax. Can I get this piece off of the main coax into the interior?? If so, how?? Is this also a piece I can get from gm parts direct, and does anyone have the part #??

Thanks for the help!!
