Originally each of these side members consists of two parts, front and rear, united by a flash-welded joint at the center. To these side members are welded the front and rear cross members, engine-mounting brackets, A, cowl-support cross member assembly, B, chassis-to-valance spacers, C, front brackets of front springs, rear brackets of rear springs, and various other minor units and assemblies.
