Hi Andrew - sorry to read about your propshaft...
Earlier in the thread you mention that a crack had been noted on the proshaft coupling as opposed to the propshaft itself (I can’t understand why this wasn’t replaced immediately.) It’ll be interesting to see if it is the coupling which has put the propshaft out of phase and turns out to be the route cause of the split.
Like yourself I’m playing catch up on what’s under the bonnet and have found this link Aero8 MK1 Parts book (mogparts.net)
Mogparts.net to be quite useful in identifying the various parts etc – page 43 being relevant to this particular issue.
Whilst this is a setback – you have a great looking car which should give you a great deal of pleasure once these issues have been sorted.
Regards Will
