The subframe assembly includes a structural top corner casting body which has a roll-up door track segment formed integrally with the top corner casting body, a top gusset stiffener plate formed integrally with the top corner casting body, and a radius top header edge formed integrally with the top corner casting body, the radius top header edge being formed to abut the radius top header at a juncture that will permit the radius top header to be lap-welded to the radius top header edge. The top corner casting body also has, formed integrally with it and projecting outwardly from it, a top corner post lug formed to be received by the corner post in lapping abutment, and a top cross-piece lug formed to be received by the top cross-piece in lapping abutment. A structural bottom corner casting body has, formed integrally with it and projecting outwardly from it, a bottom corner post lug formed to received by the corner post in lapping abutment, a bottom cross-piece lug formed to be received by the bottom cross-piece in lapping abutment, and a bottom rail lug formed to receive the bottom rail in lapping abutment.
