Well the floor is now in place and the engine is back in, here are a couple of pictures of it, it seems very study with minimal flex, I used 2mm 5251 grade ali for the floor with rivets placed every 50mm, I was surprised at how quickly I managed to rivet it in place, it took about 45 minutes from putting the sikaflex on to putting in the last rivet.
Also my mate came round and gave me a hand re-wrapping the rear wheel arch, it was so much easier with 2 people, one to hold the vinyl/use the heat gun and the other to smooth it down, it did take an hour and a half to do though, but I am happy with the results. I think I will be putting some edge trim around the edge of the wheel arch just to finish it off and prevent the vinyl from moving.
The next job on the list is to do the interior panels and run brake, fuel and electrical lines, I am ordering some aluminium strip from Aalco at the minute so I can do lines over the weekend.
