OK so i went to pick a part and picked up a rocker arm and a lifter took them home and took them apart [from a gtp] that was missing the supercharger the bearings are a different size than the one i found in my oil pan closer to the lifter size i called gm and there is a first and second design on the lifters anyone know about this my regal is a 1998 im thinking that is why the bearings are different
