Problem with Passenger Side mount for EG... HELP!

I sent my car to a friend to paint it, he was filling in some of the holes in the empty engine bay of my EG and by accident welded the holes for the passenger mount HAsport kit shut, Now i dont know what to do. I was thinking screwing in the bottome 3 screws on the side to line it up and re do the holes, but i forgot whether those holes were threaded or not. Were they? Also im still confused on how to install the passenger mount. Does anyone have pics on how? Im dumb. Thanks guys
