89 Silverado djm cnotch issues

[775stepside]

So I installed a c notch kit from djm, 4/6 drop on my 89 Silverado. Been driving it for couple weeks now and I have adjusted the rear shocks with the extenders. Seems like there is not enough play for the shocks to extend. It bottoms out with any little bump.

Another question my left rear wheel is more to the back and the right rear is more to the front. So I'm thinking I might of re installed the leafs springs backwards on one side? Any input guys?
