GM Antenna Mast Removal Tool

thingiverse

This is a tool for removing the antenna mount on early 90's GM vehicles and possibly others. I tried the tool for Toyotas and it worked but eventually stripped the drive teeth off before I turned the nut completely off. So I designed a new one. Should work on most GM vehicles from the 80's and 90's and perhaps other vehicles with a 4-slot retaining nut. The fit is designed to be pretty tight, so pound it on with a rubber mallet, and then you should be good to go.
