Power antenna for '77 280Z

Some punk broke the mast from the power antenna. :mad:

Yes, I should have retracted it but I didn't. :stupid:

I thought that antennaX (ebay) had the correct replacement mast but it is not correct. I would prefer not to replace the whole unit with an aftermarket. I have an up/down switch on the console and a two wire connector back at the unit. I have only found units with a good motor and no mast, which is what I have.

Hopefully someone out there has a unit with a bad motor and a good mast?
