my 89 ta has a bad power antenna i removed it and the motor is good up and down..the mast is bend and broken... what part do i need to change... i tried removing the mast but there appears to be a nut on the top. does this need to come out and the whole nylon and mast are removed in one piece? or do i have to replace the antenna mast and tube as a whole unit then fish the cable into the motor.... what part number do i need if my mast is shot and my motor is good. the other threads are confusing on what exactly is needed. it sounds fairly simple. but i dont have a manual on the car... thanks in advance pete
