In a B-Post Blowout, where is the relief cut made?

• A. At bottom of B post, parallel to rocker panel
• B. At the top of the A post
• C. Along the door seam
• D. At the center of the rocker panel

Answer: (A)

Relief cuts during a B-post blowout are placed at the bottom of the B-pillar, running parallel to the rocker panel. This location gives a controlled release path that reduces resistance as you work the blade upward, allowing the B-pillar to deform and separate safely without binding. It preserves the upper pillar and roof structure for the remaining steps and minimizes risk to door hardware and window areas. Cutting in other spots would either threaten structural integrity higher up, hit the door seam, or not provide the needed relief in the pillar.
