Here is the link to the parts list that several of us have been working on for the G749 series. We will continue to update it as new part numbers are discovered.
Please let me know of any additional part numbers you might come across and I will add those to the list for everyone to use as well.
If you do not have a Dropbox account, just close the prompt to log in and you should be able to view the list. You will have to download the part list to be able to click on the blue hyperlinked part numbers or just press control as you click on them.
