As Bounty Hunter said, they should fit fine, however, they may rub on the inner rear fender area.
Worst case scenario you can order up some rear 1" wheel spacers to push them outboard a bit. Some people don't like wheel adapters or spacers, but we've had pretty good luck with the ones that customers wanted us to install for them. I see both sides of the argument..for and against...but then again I run a set of adapters on my 1966 F100 pickup, and have had zero problems with them.
In an ideal world, you'd purchase wheels with the "correct" backspacing on them already, and not have to mess with adapters or spacers.
