Do take note that you won't need the 1.5" up front to match 1.5" in the rear. Since the coil is located on a swing arm, it's location wrt the control arm frame mount will lesser the spacer thickness.  The closer the coil, the lesser the thickness. The farther away, the larger the thickness.

I suggest that you add your rear spacer. Then measure the front coil height. Lift the front off the ground with a floor jack. Remeasure the exact spot. Difference will be the approximate spacer thickness.

Ive noticed that im gonna see about using 1 3/8" in the front and 1.5" in the rear and see what happens from there

I couldn't get my coil back in with the 1-3/8" spacer added up top. The swing arm didn't go down far enough. I did have the passenger side shaft still in the diff and connected at the hub. I did remove the caliper and ABS sensor, undid the upper strut mount and even the tie rod. All that didn't help. (I don't use a front sway bar.)

I just swapped out the bad housing and had to totally remove the axle shaft on the passenger side. I had to totally remove the strut/knuckle from the lower control arm. The control arm didn't fall to the ground. I found that the bushings were really tight. By loosening some, the arm hit the ground. This may help in getting the coil to mount into the arm properly. You may have to man-handle the spring into the arm while swinging it up. Biggest pain in the ass is that swing arm. I'd suggest you totally remove the front and only have the control arm and coil to work with. Add the shaft and strut/knuckle once the coil slips in. This is also no that easy as the ball joint hits the outer cv when you try to lift the knuckle into the ball joint.

I kept my 2 bolts that hold the knuckle to the strut as these bolts 'align' the front end. I can take the strut top off as many times as I care to and place it back together again and have minimal change in the alignment. Break those 2 bolts on the knuckle and you got a mess to contend with.

Its hard but what u got to do i think is im gonna try busting the inner bolts and keep the balljoint attached and use a jack and try to put the spacers up front.
