The bigger pieces are the rumble lid stops. There mounted to the floor inboard of the hinges. Some of the catalogues have the exact dimensions. The shoulder bolt goes into the hinge mounted to the lid. You should have 4 square washers two for each side the lock washer and square nut go on last the square washers are on each side of the bracket that's on th car. They are textured for extra bite so they don't slide around when tightened there's some slop in the hole in the car mount so you can do sme adjustment there. It's not a very handy spot to get into but with the right tools you can. I replaced my shoulder bolt with one with an Allen head. It was much easier to get an allen reach in there than a ratchet and socket. Good luck , FAnk
