Outer Limits 4x4 Board

Hello All,
New member here in Ireland, I have a 92 Paj SWB 2.5 Turbo Diesel. 2" body lift, simex extreme treckers, winch bumper and rock sliders. I am interested in doing the ball joint flip can anybody tell me where you put the shims in to correct the wheel alignment after the ball joint flip? Also want to put in longer shocks can anyone tell me any supplier who may ship to Ireland?
Thanks

take it to your local tyre shop who does wheel alignments and they will put them in for you,otherwise they go inbetween the top wishbone link rod and the place where they bolt to the chassis
