Need speedy Help! 72 240z Power antenna replacement

Hi there my dear z friends!

i need your help! You have come through for me on this restoration of my 1972 240z, in so many areas, and I need your help once again! 

I purchased a z appropriate replacement antenna, we installed it today in prep for the Z bash in LA on Friday. So bummed to learn that the new antenna is bad.

i plan to put a proper z antenna in upon return from Z Motorsport or the like... but Id like a working power antenna for the trip. I don't have time to get an antenna shipped in time. 

Any suggestions as to any chain auto parts or auto stereo places that might carry a power antenna I can use. Such as Oreillys.., etc? I'm in Las Vegas

Your speedy help is not only needed quickly, but so appreciated!

Ok fellow Zer's do your thing!
