Ok, so here's the panel I made from the CAD pattern, gotta say it wasn't a drop in fit. The folds are similar to square to round which is good for radius curves , a bit of guesswork and some flexing it went on fine..

Once satisfied where it will sit, I marked out it's outline and then about 20mm inside just in case something needs adjustments.


Looking underneath I hammered the floor to meet the new tunnel and stitch welded it on

And this is it all plug welded, I turned up the heat on the welded so the metal would melt together

After that was done I got the seats bolted and welded nuts to the floor. The drivers seat is electric so I used a battery charger to power it up to move back and forward, a bit annoying but hey, luxury at a minor cost. I'm still planning the rear seats install as are just too wide and the inner wheel house is in the way... I'll work a plan to make it an easy mod without butchering them to much..
