67-69 barracuda front tire width

What is the widest tire without fender modification anybody here has run on a 67-69 barracuda. I am looking at 15x7 rims on all 4 corners and know a 255-60R15 will fit no problem on the rear. What about the front. Will a 255-60 fit without the fender hitting, or do I need something along the lines of a 225-60 R15. Running 73 up BBP brakes if that makes a difference.

Please dont reply what you did as far as dart, or duster etc, simply because the fender openings are cut and radiused different, and is kinda like comparing apple's to oranges.i need to know what guys running 67-69 barracudas are using and what if any clearance issues they may be having.

Thanks
Matt
