To address structural integrity and crash protection issues, a "B" pillar was added, thereby changing the car from a true hardtop.

For the first time, none of the passenger cars had a "B" pillar, making all closed models true hardtops.

The new design "B" pillars were structurally strong enough to contribute to occupant safety of a roll-over type accident.

The skinniest strip on a car, the B pillar or ribbon of metal between the two side windows, can cost an advertiser $200,000.

Some vehicles had a slim "B" pillar between the front and rear door while others didn't.

Hardtops were no longer produced; all models now had thick "B" pillars.

Alternatively, a coupé is often distinguished from a two-door sedan by the lack of a B pillar to support the roof.

Quad coupé is a marketing name for cars with one or two small rear doors with no B pillar.

On the exterior special chromed B pillars and chrome wheels were included.

"Silver Line" was similar, only in metallic silver color with a black fascia around the back window and the B pillars.
