1967 Mustang Fastback/ biggest rims I can run?

[mtdubvee]

I am wanting to set my 67 mustang up with some 18's in the front, and 19's in the back. What is the widest i can front in the front, and in the rear, and at what backspacing? I know it will vary but it has the wilwood 12.19 kit front and rear. Has anyone done anyhting like this?

I am looking to do a staggered setup, in a nice forged wheel.

It DOES NOT have a mini tub, or any rolled fenders.

Thanks and please help.

Not sure about that 19 in the rear. But I have 18s all around with 4.5 on the front and 5.5 on the rear. Might have to rub on that inside fender lip alittle if it is lowered much
