Abstract: A tool for coupling a striker structure to a vehicle body structure in operative alignment with a latch mechanism coupled to a door structure. The tool includes a body locating portion and first and second fixture portions. The body locating portion selectively couples the tool to the vehicle body structure. The first fixture portion is coupled to the body locating portion and includes a post member for engaging a latch ratchet of the latch mechanism and an outrigger structure for engaging the door structure to thereby limit an amount by which the tool may rotate about the post member. The second fixture portion may be coupled to one of the body fixture portion and the first fixture portion. The second fixture portion includes a plate member and a latch clamp. The plate member has a slot for receiving the leg member of the striker structure with the slot having a proximal end and a generally open distal end.
