The 1970 Bristol 411 which is in the Bridge Classic Cars restoration workshop to be converted to left-hand drive has to have several important pieces in the engine bay modified to fit the application.

One of these pieces is the heater box of the classic Bristol. The inlets and outlets of the heater box, once it has been rotated during its relocation across the firewall, were in entirely the wrong orientation. This means that our restoration technicians have had to modify and relocate each of the individual outlets. Along with that, other openings in the heater box has had to be blanked off and reopened 180 degrees out.
