Will 275/60/14 rear fit on my 72' Dart?
Dartboy I am not sure where you are getting your info from but I have Super Stock leaf springs and 275/60/15's under my demon and there is plenty of room. I have 15-8's with a 4.5 inch backspacing. I would not forsee any problem at all fitting a 14-8 with the 275/60's It will be a little shorter with the inch less of rim size and you will have more room if you are not running super stock springs.
