don't forget to fully seal the trunk area from the passenger compartment you need to panel the sides between the outer 1/4's/'tubs' etc. if not fire could still get through to the sides (where the rear 'door' cards were) and also up the 'c' pillars into the roof/headliner area, both are in the passenger compartment. aluminum rear 'door' cards/panels would sort the majority but better would be to block it off in the trunk each side.
neil.
