I doubt you'll find anything from Prothane or ES that will fit out of the box, or I would have heard of it by now. I think the closest anyone got had the right diameter but needed to be cut down, if I remember correctly (which with how my memory is these days, take it with a spoonful of salt).
I'm running the Outfitter Design bushing kit. Having it mounted solidly to the chassis has been nice, plus unlike urethane that will break down over time the OD bushings are a lifetime part. It is more cost than urethane but they're very nicely made and go in easily. Getting the old bushings out on the other hand is a PITA unless you have an air hammer. Even then it's iffy.
