Lower control arm bolt?

Anyone have any good ideas on how to get the lower control arm bolt out if its rusted inside the sleeve, without having to completely destroy the bushing?

i havent had to fight with that yet, but soak in wd40/pb blaster for a week spraying everyday, and hope for the best. are the bushings expensive or hard to come by? i know you can get the upper kit for like $40, comes with everthing

Yeah I tried spraying it but that didnt work. Idk if there hard to come by, but the bushing will be replaced with steel for the new control arm. I dont want replace something that is going to be replaced in the very near future if I dont have to.
