I would say it is easier than the leaf springs, provided that your leaf spring bolts didn't give you a ton of trouble (some people have to cut the bolts). For me the leaf spring bushings were a complete pain to get in given how snug they were.
If my memory is correct, once you remove the front shock and spring with a compressor, the spring saddle will be right there on top of the control arm. Undo those two(?) bolts and you can replace it.
Rather than replacing the bushings, get roller spring perches instead as they are well worth it. I would also consider doing the shelby drop (which is a little more involved) since you'll have the springs out.
If your spring perch bushings are bad, you should also inspect the control arm bushings, they might be bad as well.
