Last year I had a slightly naive exchange with the senior scrutineer, Rob, asking him if I should not have a fireproof bulkhead separating the passenger compartment from the boot? The answer was pretty obvious if I tell you that the little foam-filled petrol tank lives in the boot, and that I'm normally in the seat in the front. Additionally, my car has a rudimentary through-flow ventilation system that attempts to flow air from the passenger compartment into the boot, and then into low-pressure areas ahead of the rear-window through side vents.
And it was all beyond doubt after removing a couple of self-tappers and pulling out the upholstered, plywood parcel shelf. Of course, I had done nothing about it since the previous year and now had three days to fix it and before facing Rob again.
The job was complicated by the diagonal of the rollcage. But those years of yoga class, and the decision to make it in two parts, definitely paid off. It also helped that I started with card templates cut from an artist's mounting board rather than trying to use cereal boxes or the metal itself.
Fortunately Gilbern had bonded in a lip underneath the back window that the parcelshelf rests on, and the seat-back panelling has a square roll over the chassis tubes that becomes the back of the boot. A strut is riveted onto the seat back and to the lip under the rear window to provide some rigidity. So I had good surfaces on which to mount the bulkhead, but they were a little ripply and I had to avoid putting the join of the bulkhead above the tubular tie.
After trial fitting, I found another complication was that the bulkhead bisected the 'airflow' vents unique to this car. I intended to keep them but decided to blank off the upper portion so they could be sealed against the bulkhead. They would then vent the boot space but nothing else.
Got it finished Friday night @ 1740. Bo'ness tomorrow and just in time tonight to go pick up one of my sons from school in 20 minutes....
