Look forward to seeing your progress. if I may ask.. How did you get the head light bowls out/free? I have now busted two screw driver tips trying to unscrew as my bowls are rock solid in place.
They were held in by screws one side post repair I think the near side I drilled the rivets that were holding it in place. Haven't checked the manual for which are the original fit. They wouldn't come out until I loosened the beam adjustment screws though.
Followed that success up with 30 minutes this evening to remove a wing mounted wing mirror. Threads were corroded to hell.
