This weekend I have welded in the cage. Its not 'bolt-out' anymore, but the extra structural stuffness by welding the A- and B-pillars to the cage had my priority
Cage is really close to the A-pillars which I really like. It makes welding easy.
I made a bracket to bolt to the former seat belt mounting points so I can keep the head liner and inner trim intact:
Next making the dash fit...
