Will 275's fit?

My Buddy Tom has 275's on his Duster with 15" X 8" Welds and I *think* stock spring location.


These are the M-T's Tom had last summer, not the 275's. But can anyone tell from this shot by looking at the springs in relation to the backing plates? I can't get him on the phone at the moment and this is bugging me. While I don't want my car looking like an 80's street freak with HUGE tires out back, I don't want space in the wheel wells.

And I have no plans on moving those springs.....
