Abstract: A unit window regulator assembly is adapted for use in conjunction with a vehicle door or body having a framework and an upright opening defined by inner and outer walls. The regulator comprises a pair of spaced transverse support brackets securable to said framework and supportably mounting an upwardly opening C frame in said opening for longitudinal and transverse adjustments within said opening. A pair of spaced elevator channels receive and supportably mount the lower edge of an upright window secured thereto. A pair of parallel spaced formed guide rods at their lower ends are anchored to said brackets and at their upper ends are secured to said outer wall. First lateral apertured flanges on said channels receive and are guidably mounted on said rods for a predetermined vertical and translation movement within the window opening.
