Rear tire width max for 67 Barracuda

Anyone? Not at all excited about dropping $340 bucks on axles...help.

PLay ur cards right , u can get 295 60 d15`s under it -----thumbnail.jpg
car is lowered now , tires are up in the wheel well about 1-1 1/4 , set w/ just a little rake now ----------disc brakes require a diff backspace , 4'' would be perfect on this .
