high misalignment shims

hey everybody, i am setting up my four link on my yota and i am wondering about these misalignment shims and how good they are. i want a decent 3 wheel if i can manage it. i have the 3/4" heim joint four link kit. any help is appreciated.

how many should i get and what size? don't know much about them but i've heard they can help out with articulation some. would i need them for all of my bars or just the ends that are on the axle? i'm trying to get it finished by kentucky havoc in aug. any help is greatly appreciated.

does anyone have any suggestions?

use 2 per end for a total of 16. as far as size, you gotta know the bolt hole size in you heim.

do you guy think it will make a difference as far as articulation? all i'm looking for is a decent three wheel on my 20's. as long as i can get the tire off of the ground a little that will do for now until i redo with the irs i have out of a supra. havoc is getting closer. would just do the irs now but i plan on going 22x10's in the back so i have to get new halves made so i can.
