Spring Isolators

I would like to lift my Liberty just a little more and would like to add an additional spring isolator at each corner.
My question is; do I get upper or lower isolators to add?

If rear you can have 3 total on top , each adds 1/2 inch of lift
If you already have 3 on top may need new springs

I run two extra upper isolators in the rear and one extra lower as well. So total of 3 upper isolators and two lower isolators. Front I'm running jba strut plate and clevis lift to level it out.

How many conduit nuts for clevis lift in the front to equal two extra spring isolators in the rear?
I am sitting at 20" front and rear and having a little problem with tire scraping on sharp turns. I think that my springs have started sagging and want to bring my lift back up.

What would be a reasonable charge for a shop to do this work? I have been quoted $450 by an independent Jeep shop and think that seems to be a little outrageous.

450 for a clevis lift? BahahaHa I need to open a shop!!

Each conduit nut is 1/8 thick, front it doubles the lift vs thickness.

So.....
Rear iso= 1/2 lift
Each c nut= 1/4 lift

So to get equal to two extra isolators lift, 1 inch, you can do 1/2 inch clevis lift.

To do a clevis lift can I just jack up the Jeep, remove the tire, undo the top clevis bolt and pry the clevis down, install the conduit nuts, slide the clevis back up and tighten the top bolt, or are there other parts that need to be undone to do the clevis lift?

I have read a couple of different procedures on the forum and just want to make sure how to do this. I don't want to get part-way into doing the lift and find out it won't work or that I have to do four more things to get it done.

I don't want to spend a lot of money at a shop to do something that I can do myself. Any help would be appreciated.

You don't really need the the conduit nuts, they are more of a 'measuring tool' than anything.
Procedure as follows:
Break lug nuts
Jack up one corner
Place jack stand
Pull lug nuts
Pull wheel
Remove lower sway bar end link bolt (18 mm )
Remove upper control arm nut (21mm)
Whack top corner of steering knuckle to break free from upper control arm
Loosen upper clevis bolt (18mm bolt head, 21mm nut)
Pry/slide that sucker down 3/8" from factory position
Reinstall everything in same order.

Edit: noticed you have an 03, if it hasn't been apart in a while PB blaster might be your friend.
