10" on a stock 73 Duster?

Hi folks,

Could I run a 295x50x15 rear tire on a Cragar V5 15X10" on my stock 73 Duster 340 without any mods?

Cheers.
Without a lot more info , my guess would be.... probably not!
First thing we would need to know : what backspace on the wheels? (and i dont mean that damn "offset"bs)
Next, 8 1/4 or 8 3/4. (Large or small bolt pattern)
Next, how much ridiculous seventies ***-way-up-in-the-air stance are you willing to put up with?
