Are the ball joints oem? rivets?.. hit em with the torches, habit ive always had with uppers was to stick em in the freezer untill ready for install, id heat up the arm and drop the frozen parts in, but only if kinda tight.
bushings: local shop could chisel em out and press em in unless your cheap like me and got lots of air and a chisel then id stick in vice, heat up the hole and set frozen bushing in...big socket over and beat the hell out of it:biggrin: ...or press em in with vice, couple of sockets one to cover inside and other to hlp press it in
