Done a bit more to the gearbox mount now.

I got an xr2 trailing arm and cut that up to make a mounting for the front of the gearbox. Then chopped up a panhard rod and used it to brace the front and rear mounts together.
Will be welding a plate between these to strengthen it up.

Also made up a bracket for the clutch master cylinder and mounted it into position. Still to make a rod up to connect this to the clutch pedal but shouldn't be too tricky!
