15X8 Cragar backspace ??

Is anyone out there running 15X8 (4.25backspace) Cragar SS on the back end of there Duster or Dart Sports, if so, any issues? I'm converting my a-body 8 3/4 from sbp to lbp and will be switching to 10X2 1/2 brakes. Looks like the change will push the wheels out by about 1/4" each side. I'm trying to determine if the 15X8 SS's with 4 1/4 backspacing will work with this combination. Besides the swap to lbp with brakes and axles the remainder of the housing is stock.
