Fixed this morning Theland.
No tradies available this time of year, parts unavailable for a few weeks.
Local tradie had a part that was nearly the same, let me take it home.
A bit of modification, I made it fit and work, 3 hours on a tin roof in 35c heat @ 5:30 am, I'm knackered, but, indoors is now cool.
Happy as the proverbial pig in it!!!
Hope you are warm ;-/
