Stock 14" Rally. What's my max width tire option?

My 73 Dart Swinger currently has 235/60-14 tires on the rear, mounted to stock 14" Rally wheels. Do you think I can bump up to a 245/60-14 without any clearance issues? I'm running stock location Hotchkis rear springs, Competition Engineering Slide-a-links, and stock fender wells with stock chrome fender trim.

Here's an image...



Also, it looks like BFG T/As will be my only option. Does anyone know of another option? If there's more option in a 50 series, I'm willing to try that too.

I would love to step up to 17" or 18" wheels and tires, but the budget doesn't allow it.

Thanks, in advance, for the advice.
