GM Antenna Mast Removal Tool

thingiverse

This tool is specifically created for removing the antenna mount from early 1990s GM vehicles and possibly other similar models. I initially tested this tool on Toyotas but unfortunately, it ended up stripping the drive teeth before completely loosening the nut. As a result, I designed an improved version that should work effectively on most GM vehicles from the 1980s to the 1990s, as well as potentially other vehicles featuring a 4-slot retaining nut. The design features a snug fit, so it's recommended to use a rubber mallet for pounding and then you'll be all set.
