Thanks for the reply. I have a full set of regular torx bits. These bolt heads are a reverse torx type. They require a female E-Star type of wrench/socket. I'm going to guess on the size being a E8 , looks like I'll be adding more tools to the box!
Just wanted to up date this in case anyone else is searching. The screw head on this 1994 is a E-8. I could not find a wrench at a local supplier, only sockets. So, I bought a single socket from NAPA, and a cheap 7\16 boxed wrench from another box store. Forced the socket into the boxed end wrench and welded it. Works good.
