Below shows the seat runners
welded into position.
In order to get the seats as low to the floor and as far
into the center, the tunnel must be modified. Chop out a
section of floor, where the old seat mounts used to be,
about 350cm long and weld in square sections each side.
The tube used is 30mm diameter CDS 16 gauge.
Make sure the bar locations are re-enforced to the tunnel
and cut into the sills where they meet the floor. To mount
the seats to the bars use 20mm solid bar 25mm long threaded
with standard M8, weld these into the tubes as required.
