Will Boss 338 (18x8/18x9.5) fit on my 69 cuda?

Need some fitment help. Will the 338s 18x8 +14 front and 18x9.5 -4 rear fit on a 69 barracuda? I have factory suspension, a 8 3/4in rear end, and a 4 piston Wilwood front disc brakes.
I believe the fronts are 4.5 backspace and the rears are 5
Any help would be appreciated.
