Body side frame assembly

Body side frame assembly
On a four-door saloon this incorporates the A-post, the BC-post, the D-post and the rear quarter section. The side frames reinforce the floor pan along the sill sections. The hinge pillar or A-post extends forward to meet the dash panel and front bulkhead to provide strength at this point. The centre pillars or BC-posts connect the body sills to the roof cantrails. They are usually assembled as box sections using a top-hat section and flat plate.
These are the flanges which form the attachments for the door weather seals and provide the four door openings. The D-post and rear quarter sectionis integral with the rear wheel arch and can includea rear quarter window (Figure 1.47).
