The one from ames won't work, According to the person I talked to. The base is not set up the same. You can buy their base and it will plug in. The original has a wire running in it. I needed the whole assembly for mine so far I have $200.00 in it. and that was luckly, sniping the mast on e-bay- N.O.S. for $110.00 if you arent worried about concorse I would buy the $45.00 kit from n.p.d. it works great just has a round mast instead of the oval and radio shack sells the cable to get to the radio.also it has a correct looking base ,meijers might have the extension too.I had to go original cause I will be judged. Good luck
