Bristol alternatives.

Yes, Bristol did on the 411, with barely noticeable bodywork changes.
That's what those two vents are for on the rear wings. There are lightly
spring loaded flaps behind those. That's also why there are two wire mesh
grilles in the rear parcel shelf. The holes beneath them are not, as this

shows, for the seat belt to pass through!

I guess this follows on from the first Cortina, which had vents on the C
pillar. A lot of current cars have vents in the boot which exit behind the
rear bumper and are therefor not visible.These have a rubber flap to act as
a one-way valve. The 403 already has airflow into the boot via the rear
window blind slot, but no way out from there. I would not like to cut vents
into the rear wings, but the areas to the side of the boot floor, behind the
rear wheel arches is a possibility.
