Welcome John. You don't need a spring compressor to install the kit. It has been a while but I think I remember just unbolting the top of the strut and pushing the lower control arm down, (you will have to unbolt the sway bar too) installing the spring or spacer, then gently pushing it all back up with a floor jack and bolting the strut back in at the top. With the rear, I got the jack stands under the frame rails and was able to push down on either end of the axle far enough to install the spring spacers. Be careful and use jack stands. Post a pic when you are done- we love pictures!
