4" bolt pattern wheels

im running a 71 duster with a small bolt pattern 8 3/4
my 15X8s have 4.5 inches of back spacing
4.375 would have been perfect
(these are what i have) U.S. Mags Indy U101 Polished Wheels U10115805445


once i get round to getting new tires put on those wheels ill put them back on, but for the time being im running my old 14X10s with N50s on them
talk about hanging past the fenders

My profile picture is with the 8" cragars on which is probably the size I will go with. 10s will be a bit much i guess. If I don't locate any old slots when the car is ready I will go with those Indys. Thanks for all the info.
