During dash displacement, where should the base of the hydraulic ram be placed?

• A. On the A-pillar
• B. Base of the B post
• C. At the roof rail
• D. On the floor near the doors

Answer: (B)

The key idea is to use a solid, stable contact point on the vehicle’s structure to transfer the ram’s force safely and predictably as you move the dash. The base of the B-pillar is ideal because this vertical post is a robust, nondeforming part of the frame that can withstand the load and keep the ram from sliding. It provides a reliable reaction point, helping you push the dash forward without compromising nearby components like the windshield, A-pillar, or roof. Anchoring at other points is less safe or effective: the A-pillar is closely tied to the windshield and can be damaged or cause misdirection of force; the roof rail is high and not designed to bear this load; the floor near the doors may be unstable or weaker and prone to shifting under pressure.
