You can't just drill holes, you have to install by brazing the bosses on the frame, otherwise the frame itself is too thin to handle threading to accept any bolt. And when you braze on a frame that's already painted your going to remove the paint from the where your going to put the boss on then probably burn the paint surrounding the area; then you would have to have the frame repainted.
