The structural carrier assembly is installed in a motor vehicle front or rear end. The structural carrier assembly includes one or more support brackets connected to one or more frame rails of a motor vehicle body. The structural carrier assembly further includes a carrier member having laterally positioned attachment clips. The attachment clips connect the carrier member to the support brackets. The carrier member includes one or more attachment mounts or locations for supporting accessories, such as engine accessories, of the motor vehicle. A cross frame is mounted to an upper end of the carrier member by welds or mechanical attachments. The attachment clips each include an integral fulcrum cup and locking tab typically formed on the lateral sides of the carrier member. The locking tabs engage mating openings formed in the support brackets to connect the carrier member to the frame rails.

A coupling structure for an air guide of a front end module includes a plurality of rib members formed at a lateral portion of the front end module, at least one support ribs protruding from a fixing surface of the air guide, and a plurality of insert blades extending at a right angle at one end of the respective support ribs. Each of the rib members is formed about an associated guidance recess, and includes a pair of lateral ribs protruding from opposite lateral sides of the guidance recess, and a pair of front ribs extending from distal ends of the lateral ribs toward each other. The support ribs are configured to be inserted along the guidance recesses of the rib members, respectively, and in such an inserted state of the support ribs, the insert blades connected thereto come into contact with inner surfaces of the front ribs of the rib members.
