Time for an update. The bell housing needed further modification to fit as having got Simon H to plate over the bit cut out to clear the chassis rail, I then realised that the flywheel would not fit. Doh!
So, it has now been re opened and a bit more taken off, plus I have welded the original piece of the forward facing mount back in. It now fits fine and there's decent clearance with the chassis rail.
However, there is not enough room for the concentric release bearing and the clutch assembly. This will mean that I will have to get about 15mm milled off the bearing mounting face so that it fits properly. Something I have since learned is quite common.
