broken antenna please help

the mast of my antenna is broken and am not shure if the motor still works.can n e 1 tell me where to pick up a mast (part# and or style)and how to check if my motor is in working order???

ebay would be your best bet of finding one froma yard plus there is the dealer some of the prices for lil things like that arent going to kill your pocketbook

thanks!!! i think im going to look at jus wondered if someone like kragen/napa auto parts had them cheaper.
