31 A sedan best rear set up and ride height

I was wondering when i put in a 4 link para, or a triangulated set up how much would it lower rear of car. With out kicking up original frame . Right now the buggy spring on top of the S10 there is a 9 " space between top of tire a 15 " rim and the fender . With installation what could i expect 4 " or 5" drop maybe . The stance i want is a little higher then most . I really dont want to set the car on the ground . Will just have to trial and error or does some one have the specs i am looking for . Also looked at the Mstg ll ifs for frt and would the stock spindles help in the fender to tire clearence i have heard about.this pic show kinda what im looking for

Ok think i found the answer its in the lenth of the coil over you use and the placement of the mount bar.
