Also started working on the tunnel, so first thing was to secure the Gearbox mount in position.
I first cut a rectangular shape from 6mm plate
Then marked and drilled the 4 locating holes and bolted the mount to the plate.
Next a slice was made on the underside (opposite side to bend) enough to make the 6mm plate flexible
Bent both sides until they formed the same shape as the mount
Weld up the 'V' cuts formed from bending
Rebolt the Mount with plate to the Gearbox and add some 50x25 box section from the main chassis rails to hold the mount. I will adding some extra support brackets to the underneath of the box section in due coarse
