Started with the small footwell panels:
The steering column will be out again at some point for the small filler panel:
Seat back - I'm going for bond over rivets - i.e. enough rivets to keep things solid, none on the round tubes, only one on each vertical side. It wont be the seat back that keeps this part of the chassis square.
Managed to break a drill bit on the bottom edge of the seat back panel - the chassis tube underneath is square (vert/horiz) with the panel at an angle - too much angled stress on the bit! 1 3.2mm bit left now (2 more on order)
Too late this evening; The next step is to ensure a good bond bead around the back of the seat panel & then under seal the lower rear joint between chassis, panel and the floor trays.
