The BB thread is english, and if the frame does not have a braze on for a braze on derailer, then you measure the seattube diameter. From that, you get the correct derailer clamp size or use a braze on adapter of the correct size and a braze on derailer. Are you REALLY sure you ought to be doing this??

Im not doing the work myself,but I still need the correct parts.Unfortunately, I have to mail order the parts and I wanted to make sure I ordered the right ones.I am totally sure I shouldnt be doing this!

DONT clamp one on. Get the braze one mount from a Giant dealer. The tubes are very thin in the seat tube, and the possibility of the clamp crushing a tube isn't worth voiding the warranty. You should see two holes in the frame where the bracket for the deraileur mounts. Hopefully you see the silver bracket mount.
