Due to the diameter of the pinion gear being larger on a 2.73 than a 3.73 ratio rear, the ring gear sets further from the pinion centerline on the carrier. To install a 3.73 gear set on a 2.73 carrier, you can usually insert a spacer between the carrier and the ring gear to move it closer to the pinion centerline. Not sure if they make a spacer for our stock rears -- here's a sampling: http://www.summitracing.com/search/?...20spacer&dds=1
