Thank you very much Andy for this complete and technical answer. As a pro, I have all the required equipment and can raise all what I want to !
Once the gearbox and extension shaft out, I'm not sure to get the engine out. Centralise the clutch is easy and should be a problem.
Anyway I will take care about all the watch points that you talked about and will let you know once the job done.
Thanks again
PS : sorry for this late reply but I thought that I would received an email once my post would got a reply...
Centralised the clutch is an absolute doddle....its as if Morgan designed a tool for the job!!
If you need them, the Borg and Beck part numbers for the friction disc and clutch cover are HB9715 and HA3362 - on a recent clutch install on 1968 and 1955 Plus 4's I was able to get these parts over the counter at my local factors for much much less than Morgan specialists.
Whilst you have the gearbox separated from the bellhousing, check the small fibre washer fitted as a seal to the bottom layshaft. They have been known to leak. I make new ones from 2mm oil resistant neoprene and glue them in with a bit of instant gasket.
