Getting them in is easy compared to getting them out....
Removal: Air hammer with a panel ripper or a cutting torch and cut or blow a couple of slots down the side of the bushing shell after the shaft is pressed out and the rubber peeled out. Some heat may be required to turn the rubber loose if they are not old and dried out. Putting them in requires a press. Polish out the bores with a sand-o-flex wheel if you have one or similar device to remove or smooth scars from removal. Lightly grease the bore then use a large socket or thick piece of plate or washer to press the bushing in. After the bushing is in the arm then you will need to support the center sleeve from behind with a 9/16 deep 1/2" drive impact socket (Perfect fit for all I've done on A and B body cars) before you press in the stub shaft(also using a good lube or STP).
