Newly purchased, Lift and steering question

[ngnaz]

I picked up this 72 Blazer and it has awful steering and suspension. I am trying to determine what I have and where to start. Not sure of the lift size or details and was wondering how I measure it to find out. Here are a few pics. It looked like it had dual shocks front and rear but the fronts are missing. Not even drive-able as it wanders so much. It has Skyjacker shocks and also a dual skyjacker steering stabilizer. Tires are 33x12.50x15 Thanks
