Porterbuilt Trailing arms, 5" drop spring, shock problems

[vegaschevy]

I am having problems with my rear end of my 72 truck.

I have the porterbuilt 2" drop trailing arms with a 5" drop spring, drop shocks from KYB which are for the 5"-6" drop springs.

My problem is my rear end feels like all spring. no dampning or rebound and rides like HELL!!!

I have the spacer form porterbuilt to make my trailing arms 2" instead of 3". Im putting it in today!. So in the pics I am 7.5"-8" rear drop and should be around 7" after I install the spacer.

My problem is I am wondering if I need the ECE shock relocaters for the the top of my rear shocks. Im sure Nate will hopefully chime in here as well to give his two cents on the lowers as I am sure the trailing arms already relocate the shocks. anyone know?

Can anyone provide a pic of a rear end with stock height and one with lowered height with shock relocaters to see what the difference is and if my shocks are just laying so far over they are providing no dampening.
I bottom out over the smallest of bump and my rear end is all spring feeling.

hope all this makes sense.
