Well it's taken a while but the dodgy 'vert spun into life again last night.
My sincerest thanks go out to......
Jason at Malcolm Miles Saab for finding me a B204 and fitting a T7 head to it for me,
Drew for watching him while he did it
Both of the above for sourcing bits at very short notice and offering help and advice,
Eddmaster for taking two days out of his own build to get his hands very dirty helping me take the dead lump out and hoisting the new lump back in (and for putting up with my bad temper when stuff don't fit
And pre-emptive thanks to Taero who has volunteered for the unenviable task of cleaning the 'vert's mould-covered roof. If he can clean this one he can clean anything. I spent 3 full evenings scrubbing only half of it and it still looks filthy.
Thanks to everyone who's texted and phoned with offers of help and support. If i'd have been a bit more savvy i could have got everyone over at the same time and never had to lift a finger
