Hi my OEM scion xb gen2 antenna broke off...as in the screw and everything is broken off. Is there a way to completely replace it with a shark fin antenna for cheap and easy? I see them online but many require you to have the screw already in tact. I need to completely replace it i think. If i could fix the screw (like lodge the old one out and replace with new one) then I could use the shark fin cheap replacements.
