Now that I am getting some miles on the car I am hunting down air leaks that I can't address on a roller as I don't get hot air intrusion on a roller!
I have been fabricating some seals using closed cell foam, the stuff that much computer equipment comes packed in. I have also used plain old Styrofoam as well.
The "B" pillar bulkhead is a major source of hot air. It comes via the shift rod tunnel that is unused on a LHD car but is open to the area behind the seats and thus to the engine compartment. A seal cut to the shape of the opening with beveled edges pushes right in and retains itself. I cut cardboard patterns to test and then used them a patterns to cut the foam. A serrated knife or hacksaw blade work well to cut and shape the foam.
Another hot air pump is the center console where the parking brake handle is. It also is open to the engine bay.
The blocks of foam will need slots cut in them to allow them to be installed over the shift cables, brake lines etc. but the foam will mould itself around the cables, etc. and provide at least a 90% seal.....much improved over 0%!!!
