335 or 315 tire with a stock width rear end in a first gen F body?

I know that the mini tubs are a must but I am wondering if the rear end has to be shortened when running a 315 or 335 rear tire?

Thanks

Nope......

You'll just need a lot more backspacing than you would if you were narrowing the rear.

Yep, it works. Like ITDORUN said above, you just need to add extra backspace so you'll have stock looking dish which isn't bad at all on a 69.

Just a note is it for a 67 Firebird. Jason I will PM your for some details and pricing on some rims.

Thanks
