Your welcome. Take your time drilling and tapping the holes. It's a good idea to run the tap in one or two turns, then back it up half a turn, then continue. The frame rails are thin, so it's not a big problem, but if you tap thicker material, backing the tap up half a turn or so breaks and cuts the metal shavings off, from the process, so they will be smaller and not clog up the hole or the tap you are using.
