5/8 bore shock, 1/2 bolt control arm

[texastrendz]

does anyone know where i can easily find a shock reducer or new inserts for my shocks, i am running the front shocks spec. for the front dropmember. the only thing is that they have a 5/8 mounting hole, my factory lowers have a 1/2 hole. not enough room in the control arm to drill them to 5/8, i have to either machine one(do not want to do this unless i have to) or insert a whole new bushing set with a 1/2 hole. any help would be great, thanks daniel.
