Will 15X8 rallyes fit my swinger??

I'm looking to buy chrome rallye wheels for my 1971 dart. I measured the backspacing and I'm pretty sure they'll fit, but i want to be sure since there is no returning special order items on summit. Is anybody running these?? Any help would be greatly appreciated!!:burnout:

the biggest thing to worry about is the total width of the tire/wheel combo, you have 4.6 back space, and the tire will probably add another 1/2 to 1 inches. i'm running 17x7 streeters with 4.25 bs, small bolt pattern by the way, and the car is lowered........total width is 9.4 inches...here's a pic,


i'm not sure if the 17x8 4.50 bs would have fit.........maybe it would have, and now that i have this tire/wheel combo on here, it looks like there's a chance that it would, but that was a chance i decided not to take...
