OK -- Not a CZ finish, so sorry about that -- but if I came across a beater to restore, I'd very much consider NP3+ from Robar Guns. Kind of like what I did to my Beretta 96 FS Centurion, but in retrospect, I'd probably like to keep the frame controls all black. This picture is of their "Norton Special" which is all upper treatment and all frame small pieces and internals (sans springs and pins).
Also shown is 96A1 (also .40 S&W) with MecGar extended 15 round magazine and Stainless 9mm barrel/locking block combo and magazine for more versatility.
Both have "D" Springs. The Centurion has the Wolfe NP3 "bullet proof" trigger return spring. Also changed the 96A1 MSH pin to the dog-bone style upon reassembly.
