need help on removing door hinges on H1
 

Hello....we are a vehicle wrap company and we currently have a 2003 H1 hummer in our shop that we are doing a vehicle wrap on. We are wanting to remove the door hinges to do a proper install but cannot figure out the tool to use to remove the hinge bolts. The bolt appears to be a 12 pt torx in which I would need a female 12 pt. torx socket in which I have never seen such a tool nor has any auto parts stores I have spoke with. I would highly appreciate any information on where to get such a tool or if there is a trick we are missing.

Thanks in advance

I believe I just used a 12 point socket
