I finally got my seats back from being reupholstered after 3 years. Now I'm putting the tracks back on the front bench seat and there not going on right. It seems the tracks need to a spacer from the seat frame to the tracks or I have the wrong tracks. This is a 75 Maverick 4 dr. Are all the bench tracks the same? If someone has tracks for a 75 can you send a picture of them.
