Lowering kit or springs

[scotts72]

Hey guys I wanted to ask here since I cant find anyone else to give some advice, I purchased a 1972 lowered and when I drove it for the first time,I found that it bottoms out the front tires and the wheels (Rims) are rubbing the lower control arms. I know the truck has 2 drop spindles but do not know anything else about the springs or shocks and I like the look. I guess my question here is go with all new stuff or just springs and shocks, my second question is do I trim the lower control arms go tubular or try spacers first. I intend to keep this truck for a long while so I want to do this right the first time.
Thanks Scott
