Problems - heated glass too much and think I melted the display glass as a clear droplet formed on the inside.
- was unable to get any glass up at all despite extensive use of the heat gun, ending up cracking the glass trying to insert a knife under an edge as the glass was not budging at all. Was able to use knife to run under the glass after that.
- some plug popped out whilst trying to reinstall the clutch cover which was difficult to reinsert, and there is little space for the cables within this cover
-the new LVDS cable was too short and had to reinstall the old one
However, after all that, the operation appears to have been a success and everything works again, including wifi, eyesight camera and the new screen.
All in all, it was touch and go, Good luck with this procedure.
Thanks for the advice ifixit.
