17 in. wheel fit question??

[national]

I have a friend with a 94 z28 that was totaled & has some nice 17x9 in wheels from it..will they fit my GN or will backspacing be way off..I dont wanna use spacers & I dont know the backspacing just know they are on a 94 camaro & look awesome..
Thanks,Brian

Way off by about 2"

sounds about right to me..just curious if for some wild reason it might fit..oh well..they are 18x9's anyways..but I figured the offset was way off..worth a try huh
