Cadillac Power Antenna Motor NOS #1474968. My brother had a 1966 Cadillac in the 1970's and had this unopened part in my father's basement for over 40 years. I opened it for pictures as it was sealed. The item is untested but you can see from the photos that is is new and from the original box. It looks like that for some reason a piece broke off that holds the mast to the motor. This would need to be potentially re-attached with an epoxy. I put it in place in the last two photos to show how it should look after re-attachment. See Photos. This may fit other Cadillac and/or GM Brands and years. Please do your own research to make sure this will fit.
