Just based on tire sizes you should have 3/4" rake in the rear.
You should be looking at that front end, it seems high. Like the torsion bars are cranked up.
Your asking about shocks and springs. What is your goal for the car? Super Stock springs are not the only spring for your car so something else may work better based on your intent with the car.
If you jack the *** up at least get the correct length shock to match.
