46 includes an inner side surface 48 that is parallel and spaced from each other the parallel inner side surfaces 48 meet at a distal end from the rounded cam surface 42 to form an inner back surface 50 the two inner side surfaces 48 are spaced from each other at a distance so that the two prongs 46 may extend over leg 17 of the c shaped body 11 and provide enough clearance to allow the locking lever 14 to pivot about the c shaped body 11 and the integral extension 28 of the clamp body 12 the locking lever 14 is pivotally connected to the leg 17 of the c shaped body 11 by means of a spring loaded locking pivot pin 16 the inner back surface 50 of the locking lever 14 is spaced from the rounded cam surfaces 42 of the two prongs 46 so that there is a clearance between the outer surface of the integral extension 28 and the inner back surface 50 to allow adequate pivotal movement fig2 shows the preferred embodiment of the door stabilizer clip engaged to a door window frame 26 within the channel 34 of the cantilever extension 30 and a welding flange 20 of a vehicle frame 22 engaged within the cavity 18 of the c shaped clamp body 12 the locking lever 14 is shown in solid line in the locking position so that rounded cam surfaces 42 are in engagement with the welding flange 20 in phantom the locking lever.
