Shame I didnt see this last weekend as I could have got more relevant pictures before I bolted it all up!
Whats needed for the t9 bell hosuing to t5 route....
t9 need machining as noted already, an adapter plate made and a spigot bearing extender made due to the thickness of the adapter plate
Other fix is the mustang ii v6 bellhousing(from the us) but this is even more work than the t9 conversion.
