Strut and Shock Rates For 83 Z/28

Has anyone done any research regarding the factory strut and shock rates for the 83 Z/28? I would like to get replacements that are close the factory specs. I know there are several performance combinations available, but I don't want anything too stiff.

Another thing I remember when I ordered the car, is that the front strut piston/rod was thicker on the Z than the coupe. Are the performance struts the same size? I haven't seen any aftermarket struts designed for the Z/28 only, so I am going to assume different sizes will fit all third gen Camaros.

Thanks!
