Installing a lift is not hard if you pay attention
BUT if you have never done one and have only screwed a set of plugs in a lawnmower then its a huge job.
Do you have the tools for the job?
So we don't know what your skill set is so hard to say for you. Me , I tear mine out just to see if waxing them makes it ride better for fun some nights
Fronts take to a shop to have them compressed
rest is unbolt and reinstall basically.
You'll get about 2.25-2.5 inches of lift with nothing else added to them. 3/8 inch Clevis gives you another 3/4 of an inch, `1/4 inch top plate another 1/2 inch etc
All has been explained/ talked over/ discussed many many times on here
Did you order bumpstops for the front and hockey pucks for bumpstops in the rear ?
There are folks all over who have installed theirs or helped, get a Lift M&G going and maybe someone will help you
Helps to fill everything out on your profile etc so we know where you are and what year you have to work with
After cheating a little,
there are a lot of folks in your area that have lifted and may help . Buy Pizza and beer 
yep.
