Assembly of subassemblies having a mating bond interface for a motor vehicle

An assembly of subassemblies having a mating bond interface for a motor vehicle, the assembly comprising:

• a composite molded first subassembly;
• a composite molded second subassembly;
• and
• an adjustable mating interface for coupling the subassemblies together, the interface including a groove and a first flange disposed on the first subassembly and bonded within the groove wherein the groove is sized and shaped relative to the size and shape of the first flange to allow a bonding position of the first flange within the groove to be adjusted during assembly of the subassemblies so that the mating interface is adjustable wherein the first subassembly includes a first opening which extends into an interior of the first subassembly from an exterior of the first subassembly, the first flange extending about the periphery of the first opening.
