A bottom door slide includes a bracket having mounting portions for mounting on a door and providing a channel opening at the lower end of the bracket. Slidably seated in the channel of the bracket is a slide guide having a guide portion extending below the bracket and having a lower end adapted to extend within an upwardly opening channel of an associated floor track. The guide portion provides a mounting recess spaced upwardly from the lower end in which is seated a slide block having an arcuate upper surface abutting the upper surface of the mounting recess and a lower surface adapted to ride on the upper end of the floor track. The slide block is slidable on the upper surface of the recess to align itself on the upper end of the floor track.
