Made a small heatshield with what I had left. Not ideal, but better than nothing.
Sufficient air gap left, hopefully combined with the heat wrap, it'll save the alty.
The crankcase breather took ages, had to make a 90 degree elbow for it to route properly.
Engine is off the stand, flywheel (skimmed) and new clutch has gone on.
Gearbox, coolant pipes & loom to attach next week.
